well, i am hoping the straight one will put the filter behind the rear quarter like the curved one does... I am going to see if i can find some pictures of both kits actually on a honda, i figure if the filter is in the same place at the end, it should work??

My friend has an exhaust shop and he made me a nice and shiny one for 40$ tapped and all I may have him start making them and marketing them for the stock engines and if I could see someone elses DOHC I would have him make them for that application as well... and market for 75$ shipped to your door and I dunno about the cost of the filter cause my little K&N cone filter was almost the same price as the custom tube... but it happens

Tuned Short Runner Intake project for the Fiero DOHC the K&N filter is not a conceit...I'd be the last to throw one on for looks. They are loud, they attract attention, they look dumb. They hurt my ears. If you use science to determine how you should make these decisions, like making some runs with Diacom, for instance, and measuring your vacuum at WOT, you might be able to prove whether you really do have any restriction up at say, 6000 RPM which might be causing you some power loss. With this intake, you worry about power losses at 6000 RPM and above, believe me. I was seeing 30 or 29 Hg dropping down to 28 or 27Hg when this motor was stock. When I put the intake on, it got worse, down to 25Hg at WOT and 6000+ RPM. This was actually good news!! Why? The intake was doing it's job: sucking more air at higher RPMs. The Fiero air cleaner and water separator had finally shown their weak side. Fully adequate for a 2.8L pushrod motor, they restrict the air a motor like this can pull.
I put a K&N filter on it, and not ONLY did my pants seat feel better, I could measure (MEASURE--folks) a good 30-29Hg at WOT at 7000+ RPM.

The Fiero already has a very good air intake. I assume that air intake thingy would place a cone filter in the engine bay? That's not something you want.
Thats Not A Very Good Reply ....
1 It Doesnt Put It In The Bay 2 This Thing Gets Way Better Flow Than Stock ....All You Have To Do Is Look At The New Piece Compared To The Old Pieces...I Have No Numbers However ...One Of Us Fellows With The Crx Intake Should Get On This lol

removing the water/sound baffle on the stock fiero helps a little but for my HP goals a change was necessary this was a first fabrication on the guinnea pig car.
I used a 3" 45 deg alum tube and a common size K & N filter total cost was $ 90 CDN and 1 hr
this setup puts a 3" diameter pipe in the stock location

I know of at least one 300+hp v8 Fiero that used the stock air breather successfully.
The water separator can be removed and it should perform as well as the DOHC needs.
As for looks and sound, the CRX is way better. BTW, the CRX does not run hot as was stated in some other threads. The only downside to it is that you have to get at the filter through the wheel well to clean it.
I wouldn' t really hesitate to use one again. I see it as a bit of an upgrade, and I think it flows a little better. IMHO.
