ok, so I wannabuy a cold air intake with the cone filter and I saw what I wanted from both K&N and AEM but neither made the part for my 1990 RX-7 what company makes the cone filter attached the the cold air intake besides K&N and AEM, I checked Mazdatrix and they didnt have what I was looking for, I knew this was the place to ask

Theres a visual aid

How would it be rigged up? Just buy an adaptor and cone filter and you should be fine.

Theres not much really of a way to work with different setups especially with the AFM position.

Alright then

Takahasi_Ryosuke

Alright then, thank you

ok....for a cold air intake on these cars...you have to get out a saw/torch/something and cut metal to run the piping through. there isnt really a way around it unless maybe you set back the radiator? most people settle for a cold air box built around a filter. ive heard of one cold air intake sold for the rx7 which is like $300+ and a total ripoff.

cone filter intake kits are made by HKS/Apex'i/Bonez etc and are around $100-150.

for the cheapest route while using quality products, get a K&N filter with the right sized neck and a hose clamp and just stick it on your AFM. if you have your cats/airpump get a little breather filter for the airpump hose as well.

wow they lowered the price on the cold air intake...it used to be over 300 bucks.

Why do they recommend Tii injectors, just for a intake

an N/a don't need TII injectors unless it is heavily ported.

With the removal of my former Headlights and Motors, to make way for the EB Kit, I have a massive void there. I'm able to cut a hole In the wall (that seperates the back of the Headlight to the Engine Bay) and fit a custom 3' polished aluminum pipe with couplers that ends at the Brake Duct. I have all the parts right now but am waiting to Install.

Takahasi_Ryosuke/// I've searched myself and found no one makes these extensions except Checkpoint Engineering.

Little pricy for me. Besides I followed an alternative route to checkpoint. In terms of where the Filter Is going to end. http://www.checkpointmotors.net/Prod...ubcategoryid=1

I posed the same question to Chris of Checkpoint. He had said with the S5 VDI feature would case the Motor to run very lean.

vectorminds

shouldnt the engine see more air coming in... since this is all going thru the maf... and compensate for the increased air with more fuel...

or is the computer not that smart?

i am curious of this as well..

rx7raca

what about the afm on the s4? dont you have to get a stand alone in order to take it off? or how does this work? i want more air flow but i hear u cant take off afm so what do i do then?

You cant take the AFM off of the S5 or the S4, ther ECU needs its input to run properly. You just need an adapter plate on the S4 AFM, thats all.

It's BS. Ignore it.

This Is turning out to be the exact same route as the previous thread, In regards to a Cold Air Intake, when I mentioned Checkpoint Engineering mentioned the use of TII Injectors were to be used for s5's.

Perhaps someone local to Chris can get more detailed Info pertaining to this subject or have him chime In on this subject!

NZConvertible

I hope he does. I really want to hear an explanation for needing 10% more fuel for this air filter, when no other filter seems to need it...

vectorminds

i spoke with him (or someone else at checkpoint... but i think it was him) on the phone about a week or so ago, and he said that you either need to get an s-afc or something else to adjust the fuel, or just get the bigger injectors, because he said it starts leaning out....


although i had always thought that the s5's went rich when you did intake / exaust mods

NZConvertible

The factory mixtures are already conservatively rich at full load. It makes no sense that the addition of a cold air pipe and filter, which would probably add less than 10hp, is suddenly going to cause the mixtures to go dangerously lean. Suggesting the VDI is the culprit for this is even stranger. There are plenty of S5 NA owners who have fitted pod filters and cold air intakes (similar end result) and none of them have posted about popped motors as a result.

rx7freddie

theres a place that sells whatyour lookin for but its 300 dollars . im not home when i get home i`ll post the link i dont think its worth 300 but whatever just get a k&n kone you`ll be fine .

rx7freddie

this one is for the na only . so i dont care about it cuase i just got a turbo 2 87 but heres the link . if u get this and then get that other one that gos under the bumper for like 200 you`d have a 500dollar cool intake how cool will u be then hahahha whatever its all good .

So thats two places that sell the cold air Intake.


I really think you'd save more money If you were to fab up the setup yourself as I did imo.

NZConvertible

The only advantage that second one has is looks. The stock plastic pipe is huge, so there'd be no performance benfits. $300 is obscene for no gains. I also don't see an AFM...
