Anyone have a comment on the best plug wires to use? Please state why! I hear a lot of good and bad about magnecore and MSD. I heard the NGK's are great. Any input?

ULTRA 8mm Silicone Ignition Wires
1993-95 (5000 Ohm Resistance)

Racing Beat’s ULTRA 8mm wire sets are constructed with zinc-plated high-strength copper wire to prevent corrosion. Threaded brass connectors are crimped to all wire ends to provide a superior connection. The silicone rubber used will handle over 100,000 volts and is capable of withstanding temperature ranges from -60 F to +480 F over exceptionally long periods. ULTRA Ignition wire sets have a wire wound resistor encapsulated in each spark plug boot. This feature reduces electromagnetic radiation.

To obtain reasonable horsepower gains while curbing radio interference from your ignition system, we recommend the use of resistor spark plugs with our ULTRA 8mm Street Ignition Wires. To obtain maximum power gains from our ULTRA 8mm Race Ignition Wires, we recommend the use of non-resistor spark plugs. We offer ULTRA Ignition Wire sets for both street and race applications. Street wire sets combine excellent radio noise suppression with high performance (5k Ohm,- 6k Ohm) while the race provides lower resistance (0k Ohm,- 1k Ohm), with substantial radio interference.

NOTE: Some aftermarket performance spark plugs have proven to be unacceptable in terms of manufacturing quality; specifically, these plugs develop compression leaks between the porcelain and steel subcomponents causing both premature spark plug boot failure and genuine horsepower losses. For this reason, we strongly encourage the use of the factory or Racing Beat’s recommended spark plugs only for use with our wire sets.

Note: Access to the stock 1993-95 wires is very limited. Installation of these wires requires basic mechanical skills and can be completed by following the supplied step-by-step installation instructions.

 

Some people have had fitment problems with the Magnecor wires (like the wires popping off while driving) which is why you hear bad things about them.

I haven't had that problem personally, but you just need to make sure that they are attached securely. Make sure to use some dielectrical grease as well no matter which wires you go with.

 

Dunno bout an FD but i'm bout to install some Magnecor on my FC as well, will give feedback.

 

The Magnecors fit a bit loose - at least compared to NGK wires which fit nice and tightly and click into place.

For my power levels (310rwhp), the NGKs are work well and fit perfectly.

 

I've had the exact opposite dealing with them in which it's difficult to snap them into place. This is where most people have their problem as if they don't snap in, they just fall off while the car is driving. I purchased a new set of them about 2 months ago and went through it again.

 

The NGKs do take effort to get into place. No doubt about it. The difference is that you KNOW they are in there. The Magnecors, I just never knew they were pushed on far enough.

I once thought my plugs were going or an ignition problem was developing b/c the car wasn't as smooth as normal. Turned out that I had not pushed one of the Magnecors on far enough and it slipped out a bit decreasing contact with the spark plug. that plug was dirtier than the others b/c it wasn't firing.

 

I think that just comes down to the individual. I don't have a problem knowing when the Magnecors are on (or not on). However, getting the front ones on in that tight space proves to be a challenge sometimes with those plugs as they aren't the easiest plugs to snap on.

I've run stock NGK plug wires up to 19 psi/475ish rwhp with zero problems. Stock plugs and coils, HK$ Twinpower.

Having said that, I may give the Racing Beat plug wires listed above a try on my forthcoming uber-motor build

 

My builder chose the Racing Beat wires on my last rebuild. The last time I changed plugs, the silicone boot on one of the wires came loose from the connector. The problem with this is that the elbow in the RB connector isn't a 90 degree angle, it's more like 45 degrees. So when the boot comes loose, it's stupidly difficult to get the wire to snap on the plug. If you look at a picture, the boot has a bump where you push on it - well there's nothing under that, so you're pushing on the boot to attach the wire to the plug, and they're relying on some adhesive to keep it together. Very poor design, I definitely won't buy them again.

Stock NGKs are the way to go.

 

I've had the Magnecors and they are high quality but don't fit like the NGKs. I have heard of others having problems with the RB's as well. I now use the NGK Racing Cables and they fit like the regular NGK cables and are lower resistance than the Magnecors. I have no static on my radio either. High quality, high tech, high price, well actually the price has come down. Corksport has them for $81 a set now...

go to www.sparkplugs.com they have the NGK power cables for $66 hurry befor the sale ends.

 

ive always bought NGK

 

Wow, That's a great price! These wires were over a $100 and hard to find not long ago. I'm tempted to buy a backup set at that price.

 

What's the difference?

 

What improvements, if any, over stock? I just put new stock Mazda on when I rebuilt a couple of years ago.

 

I wrote a review on the NGK Powercables a while back...

https://www.rx7club.com/showthread.p...K+Power+Cables

They aren't going to magically give you 100 HP or solve ignition breakup problems by themselves but they fit perfect and are of very nice quality. Too many other RX-7 owners have had problems with spark plug wires but I haven't heard of anyone having a problem with these. The only complaint I had about them was the price and that has dropped to affordable. Many use the stock OEM NGK wires because they fit and work flawlessly. The Power Cables seam to do the same but should be a little better because of lower resistance and better quality insulation without inducing noise in the electrical system/radio.

 

I used the factory NGK wires, and I havent had any problems with them and ive driven all of the place. People have used stock plugs and wires with 200-400 RWHP with no problems as GoodFellaFD3S mentioned. I say go with the NGK's

 

Is There a life expectancy on the wires, on how long before you switch out for some new ones? I know the plugs may last up to 6 months.

At least for NGK plugs that is.
I wanna try magnecor but i agree i'm still using some old NGK's that never failed this far.

 

Visually inspect the wires for damage like breaks or melting. Also, you can check the resistance. The resistance should be similar to the other wires of the same length. Good quality wires should last for quite some time and low quality wires should be replaced as soon as they are installed ;-).

NGK Powercables #1

Magnecore are junk, bigges waste of meny ever, the boot ends split after about one year, if that

 

Exactly what happened to the RB wires in my supercharged Miata, and I agree 100% about the NGKs.

 

Sounds like someone didn't use a little dielectric grease when installing their wires. Don't blame a poor installation on the product.
