AFE Cold Air Intake, YES OR NO?

[sparker]

I looked into CAI's for some time and was well aware of all the pro's and con's listed above. So with all this in mind, I designed my own intake to be as good as it possibly could be. This is what I came up with:




Made completely from carbon fiber, heat soak was no issue (no was weight!!). I used a BMC carbon enclosed cone filter capable of flowing 650hp (no restriction there!) and I use a carbon ducting piece to seal completely onto the factory opening in the rear fender.

Gives brilliant performance, incredible sound, no heat soak, no sucking hot air from engine bay and filter maintenance is negligable.

That for sure is a nice piece!!!!

Thanks! Also has another carbon elbow at the throttle body end which is not in picture. Certainly looks a treat to be hiding under all those layers of engine covers!!!

P.S. Also not pictured in this early mockup is the AFM. That was cut off original airbox and is placed between the filter and first elbow in these shots.

The sound just behind your head is intoxicating. It is worth whatever you pay and whatever additional trouble it might take, IMHO. The only downside is decreased mileage using the accelerator as a radio

It looks like a work of art. You should consider mass producing it, so other boxster enthusiast can purchase one .

Stunning! I am now too embarrassed to post my little piece. How did you seal the inlet mouth?

I am running a BMC CDA airbox as well, but with the X51 3.8 in my car, the only place I could fit the actual filter canister was wedged up by the intake manifold, so I ran SCAT hose up to a scoop from Kokeln. From the CDA up to the throttle body is all AL hardpipe and silicone elbows/ joiners.

That carbon work is SEXY, however.

Thanks guys, appreciate the kind words. I just sealed that angled piece off with stick on foam and tape.

I have more straight carbon tube, elbows and 80mm silicon hose if anyone is keen. (Just fit your own filter to the other side of the MAF) being all carbon though, it ain't cheap!!!

Everything in my setup is 3.5"(89mm) until it necks down at the throttle body to 3.25" (83mm).

Yeah that might be better on the big motor. On my 2.5l the intake was 80mm that was reduced in a few places. So to keep the MAF measuring right I used a mix of 80mm and 75.5mm gear.
