NGK Spark plugs =

 

i think it wouldnt happen..he talk that he need 10 payments..
i hope for business but ..when nothing happen...hope he refund the money.
I think he is an good businessman and kooperative..

 

Thank you for your understanding. We do not throw out a promise for nothing. If we promise you a good deal on parts, we will stick to it.

All items have arrived at our storage for those of you who already sent me the payment and they are ready to ship. Nik's orders will be placed after the new year.

Since the admins have not gotten back to us for updates on GB fees, we will probably close this GB due to the lack of additional interests. If you wish to jump in on this deal, please contact me before January because Nik's orders will be the last one we place for this GB. Any orders come after that will be considered an individual order instead of GB pricing. Thanks!

 

Can you get the wiring in a universal style? as in to cut to length and what not?

 

do you mean some sort of a DIY plug wiring kit? Please PM me with more details about your request and we can look up something for you. Happy holiday!

 

I have the 9's and 10s for my Fc DD, and i am very pleased with it.

 

yep, these are definitely some top of the line plugs for Rotary and these are extremely rare in the US. So don't miss this offer if you need some high performance plugs.

 

is this offer still available? i am interested in 9s or set of 9s and 10s. Actually im not sure some guy said im good with 9s but im not sure with my mods. so ya please let me know

 

Just like to say we ran a set R7420s in the race car for the whole season without hiccups. They are great plugs and unbeatable for the price in a racing or high HP application, just wondering if there's any chance of another GB or if you can source them individually.

I can post pics if people are interested, no wear on the electrode or on the ground strap.

 

not gonna be another GB unless enough interests are generated. However, you can always place individual orders with us any time. Just let us know!

Nik introduced me to these plugs and this link.

So Interest in a few Sets.

1-Nik not sure yet what he wants.
2-Ian 1 set of 9's and 1 set of 10's (Pending price)
3-Marco 2 sets of 9's 2 sets of 10's
4-Dave 1 set of 10.5? for a three rotor. (Pending price)

So what are the prices if we do this. I personally don't care to wait for a GB. I would rather just call you and ship. We have up to 9 sets right here pending costs. I know the dollar sucks A$$.......

(Heat range for Me and Dave may change.)

Ian

 

1-Nik 2 sets of 4x R7420-11
2-Ian 1 set of 9's and 1 set of 10's (Pending price)
3-Marco 2 sets of 9's 2 sets of 10's
4-Dave 1 set of 10.5? for a three rotor. (Pending price)

 

If we get ten sets, then we can setup a GB price for you guys. One question for you guys is how you want them shipped? Are all orders from Canadian fellows? If so, I can have them ship the entire shipment straight to Nik, then you guys can figure out how to distribute the orders. How's that?

Since the US currency has gone down really bad since the last GB, the lowest we can do for ten sets order is $129/set of four plugs. And you guys will be charged the actual shipping plus a small packaging charge from Japan.

Also, just a concern regarding the Dave (the three rotor customer), one set of plugs only has four units, is he aware of that? If he wants to use them for all three rotors, then he will have to order 2 sets.

For others in the US, this is a good chance to get these plugs now at a discount since the Canadian fellows are helping out to get this GB setup so you guys can share the discounts. And if we get more orders, we can possibly drop the price slightly more.

 

Dave is out due to not being able to split the sets. No point in having to extra plugs.

I gather its just going to be full price for us.

Ian

 

Alright, it is totally up to you guys if you would like to get this going asap or wait for a little longer to see if any US ppl are interested as well. All we need is two more sets which should not be too hard to get. Let us know what you guys think!

 

I might be in for a few more sets. How many more are needed to get a canuck GB price?

 

We need two more sets to fill the ten set GB requirement and the GB price will be $129/set (shipping not included).

Due to the weak US currency right now, this is really the best price we can do for only ten sets. We recommend those who are interested in these plugs jump in to help reduce the prices. If we hit 15 sets, we can try to drop the price slightly more assuming the US currency does not drop too much by then.

 

Any other Ontarians interested in 9's and 10's? I'd be down for 2 9's and 2 10's plugs, if someone else is, we could split the two sets.

 

What makes good ignition? Ignition occurs in a modern automobile when an arc is struck and current flows between the electrodes of a spark plug, or when current migrates across the conductive medium in a surface gap plug. While that may sound simple at first, the process becomes progressively more complicated as engineers try to optimize the type of spark plug with the ignition system generating the required voltage.

The amount of voltage necessary to arc the electrode gap is set by the following characteristics:

The size of the gap... arc-over voltage is roughly proportional to the gap size
The air/fuel ratio within the gap... the richer the air/fuel ratio (more gasoline vs. Air), the lower the required arc-over voltage
The compression at the moment arc-over is to occur... the higher the compression, the higher the required arc-over voltage
The composition of the electrode... certain metals for all the same conditions stated above will require less arc-over voltage than other metals. For example, platinum requires less arc-over voltage, all other things equal, than does steel
The shape of the electrode... the sharper and more jagged the shape, the easier it is for voltage to jump
The amount of fouling deposits trying to remove the electron flow from the arc... more fouling deposits and lower resistance to ground pulls more energy out of the spark gap.
While it may therefore seem desirable to lower the required arc-over voltage, since without arc-over there is a total misfire and no ignition, low arc-over voltage produces low spark power because spark power is directly proportional to arc-over voltage. That is, by doubling the required arc-over voltage, you double the instantaneous peak spark power, and the higher the spark power, the better the ignition.

All ignition is, therefore, a balance between the requirement to have sufficient arc-over voltage and increasing peak spark power for better, quicker ignition.

What benefits to specialty plugs bring to this mix? One popular specialty type is platinum plugs. The primary advantage of these plugs, especially when used in an OEM ignition system (especially an older system, which may not be producing as much voltage as when it was new), is that platinum will require less arc-over voltage and therefore, particularly in a weak ignition, allows the gap to be jumped a higher percentage of the time.

For example, if at factory gap and with steel electrode plugs, it requires as much as 18,000 volts five percent of the time to jump the arc... due to the changing engine environment and running conditions... and if the OEM only produces 17,000 volts, then it follows that five percent of the time there would be a misfire.

Now, if one installs platinum plugs, which may only require, say, 13,000 volts to arc, the five percent misfiring with steel plugs would be eliminated. Since the ignition output on OEM ignition rolls off as rpm increases, platinum plugs in this case would allow the motor to reliably turn to higher rpm, thereby giving and increase in performance and possibly gas mileage.

The disadvantage of this method of reducing misfires is that the higher arc-over voltage, the better the spark when it does fire. Therefore, platinum plugs will show a performance improvement with a weak ignition because the benefit from reducing the percentage of misfires more than outweighs the loss from reduced spark power.

SplitFire (split electrode ignition) plugs also reduce the amount of arc-over voltage, but they do this in a different way. Rather than using a different metal as the platinum plugs do, a V is cut into the ground electrode, thereby giving three more "pointy" areas for the spark to jump from. It is this increase in the number of pointy areas available to the electrons migrating from the center electrode to contact which lowers the arc-over voltage. All the advantages and disadvantages of platinum plugs described above are inherent with the installation of SplitFire plugs.

While certain geometry's of electrode design, such as splitting the ground electrode, have gained popularity, the principle behind all unusually shaped electrodes is virtually the same. That is, spark likes to jump from and to pointy objects. Therefore, the pointier the object, the lower the voltage to arc over. By the way, this explains why newer plugs often increase miles per gallon and performance: the center and side electrodes are cut sharp, but after being used for many miles, the constant flow of arcing electricity invariably tends to round them off.

Surface gap plugs, which provide a solid-state medium for the electrons to migrate across, generally allow electron flow, regardless of spark voltage. However, they do not allow the air/fuel ratio 360 degrees of contact area with the migrating electron as is accomplished with an open gap type spark plug, but rather only 180 degrees. This is because 50 percent of the electron path is shrouded in the solid state medium. Like platinum and split electrode ignition plugs, they mask a problem inherent in weak ignitions.

Jacobs Electronics, a manufacturer of aftermarket ignition systems, has performed extensive testing of assorted spark plugs. They have noticed an increase in horsepower, on some occasions, with weak ignitions using specialty plugs. However, Jacobs' testers measured no advantage to using specialty plugs with their Energy Team, Omni-Pak and especially their Ultra Team ignition systems, and in some cases noticed a slight loss when specialty plugs, at the same gap, were installed in the place of standard steel plugs. On the other hand, Jacobs has seen a gain with specialty plugs when their lowered arc-over voltage has allowed users to increase the plug gap above that possible with steel electrode plugs.

For example, Jacobs tested a 253-cubic-inch V6 engine, which was slightly modified; the factory called for a 45-thousandths (0.045") spark plug gap. With stock ignition, it produced 168 horsepower. Platinum plugs increased horsepower to 171. SplitFire plugs also brought horsepower to 171. Surface gap plugs increased horsepower to 172.5 - actually a little closer to 173. Jacobs then installed an Ultra Team and replaced the steel gapped spark plugs; horsepower increased to 180.5. Retaining the 0.045" gap, the testers installed the specialty plugs, and the horsepower fell to 178.5 for all three types. The reason for this power loss was because it required less arc-over voltage at the same gap; therefore, the peak spark power fell slightly.

Further experiments with the Ultra Team and different spark plug gaps produced some interesting numbers. With steel electrode plugs, the peak horsepower achieved was 186 at 0.063" gap. With SplitFire plugs, the peak horsepower achieved was 184, but it required a 0.067" gap, which caused some concern about the piston contacting the side electrode. The platinum plug achieved a peak horsepower off slightly under 185, with an optimum plug gap of 0.066".

So what can we conclude? While specialty plugs can mask the effect of an inadequate ignition, so can reducing the plug gap in many cases. One of the true tests of a good ignition is to install a specialty plug instead of a standard steel electrode plug; of the performance of the engine significantly increases at factory spark plug gap, then the ignition was either inadequate or operating in its marginal range.

While these numbers won't apply to all engines, the results are representative and explain the balance between lowered arc-over voltage to assure a spark actual jumped, and increased arc-over voltage to get higher peaked spark power. The general rule is, the better the ignition system, the less benefit that will be achieved from specialty plugs, unless the installer is willing to go with monstrously large gaps.

Naturally, in certain situations, like when you're campaigning an older car (assumably with a weaker ignition) in stock classes where other ignition modifications are not allowed, testing specialty plugs would make a lot of sense.

 

come back!!! haha

 

(looks up...)

trying to revive a 2 year old thread? plus the fact that its been over a year since he has posted and took peoples money and hasnt sent any parts out to customers.
