My first time posting a 'before and after' style thread with pics. I'm very new with PIP so plz forgives if this goes awry.
Got the CRX CAI off ebay for $36.00. I picked yellow couplers to go with my plug wires. It came with a 'reusable filter'... but I wanted name brand. And more sucking noise surface. I called Summit with a few measurements and they have nothing like I want in stock. They special order me this:
I'm really digging the Xtreme top. Hooyeah. Internally it has a very nicely sculpted bell that attatches to the pipe. The old filter was squared off inside. Check out the number of pleats difference between the two:
When you pull the wheel well liner, this is how the CRX CAI intake looks. I cut up an el cheapo grande Pep Boys rubber floor mat to seperate engine bay from the 'airbox side.' I did not like how severe the downturn of the pipe was:
Why have an Xtreme top and have it facing the radiator pipe? I wanted to get the hoover as close to the Holley side scoop as possible:
A little time with the dremel and about 4" of pipe later... I get this. Also if you can... answer my question, please do so. Here you'll see the end result:
Here she is from the top. I like it! If they made plexiglass scoops, I'd buy 'em just to show of the super kick butt K&N. That thing has more filter area than the filter on Boomtastics front mount motor.
Hope ya'll enjoyed. You can hear me suck from a mile away

I've only owned up to 86's, but it looks as though u have an 88, and that is the ebrake cable. It runs thru the front frame section there, rather than the rear like on the early cars.
A bit of surface rust doesnt' seem like it would hurt, as long as the cables aren't binding up.

I need to give you some cred... it was actually a thread you posted about a year ago that made me want to do this. I think you even linked to some ebay auctions for others to follow your lead. AND you may hae more disciples than you know. At the Ruckus 2 weeks ago, a lot of Okies were looking at the intake and asking how it was done. When they learned how easy and inexpensive it was, they got very excited. So "thanks" from way back then.
I (+)'d you long ago or otherwise I'd give you another.
You rock.. your pictures are awsome. Im actually thinking about doing this myself as part of a winter project, however im not going to use a CRX tube.. probly some of that high temp vacuum hose and a short ram tube. then I could route the filter anywhere i need Im just kinda curious if this stuff will keep from melting with the temperature it gets under there..

Z, unless that hose is smooth on the inside which it looks like its not it will totally defeat having a K&N. You need a smooth pipe with the least amount of drag possible to help air flow through the tube. Just like port and polishing, making a bigger smoother surface for airflow.
Im pretty sure its smooth inside.. ill just have to look I havent bought anything yet, hehe

having the filter hanging out down there arent you gonna have trouble with roadcrud,grime and water thrown up on it?
that what i was wondering, wouldnt the water wash the oil (the crap u put on to get the fine particles) right off? Is it possible to put a shiled between the tire and the filter?

i have this stuff on Ling. if it can flow enough air for a 350 at 6000 it should flow enough for a V6.

Looks like when you put the wheel well liner back in, the filter will be protected. Looks good, bet it sounds good too.

are you still using all the original sensors or did you have to disconnect some of them. I have a K&N filter in the stock housing in my 88 but the scoop looks pretty cool. i would think a mesh screen would help with some of the dirt without effecting the performance. Also did you add a few drains to alow water drainage incase of rain or a big puddle.
I have no drain in mine. The bottom half of the filter gets soaked, but the top rear half stays surprisingly dry. I drive in pouring rain and have no problems.
Its a very debatable topic. Some people thing its really dumb, some think it looks/sounds cool. Guess its just up to you.

Hey Splinez, where did you find that tube? I have a K&N filter, but on a real short tube that keeps it inside the engine compartment and I'd like to move it out by the scoop there to get actual cold air. Thanks for info!

rgeeinc- I'll get that K&N stock number later. It was about $65.00.
SplineZ- You seem to have taken a real interest in this. I would recommend it if for nothing else to clean up the engine bay. It seems like I have a lot more room. You asked about the vacuum hose. It is probably okay, but if you look at my last pic, you will see how close the intake gets to my Y-pipe. I personnaly would not like anything fleixible pastic too close to that Y-pipe. Also, some people are concenred with 'heat soak' on the intake. I have run my car for hours, popped the decklid and laid my hand firmly on the intake pipe. It is hot, but not so hot you have to remove your hand in pain. So your tube idea is probably okay... I just dont like to see meltic plastics on exhaust... you know? You could always use some header wrap or aluminum tape for additional heat protection.
Hotoz- grime? well, You dont have to worry too much about that bcz the water washes all the grime away j/k. It will get more dirt exposure, but my filters get cleaned every 15000-25000 miles... much sooner than K&N's suggested 50000. Honestly, If I was worried about clogged filters or vapor lock, I wouldn't have done this. Hundreds of Fiero's have similar setups. WCF has sold numerous of their tubes. A lot of v-8's have a filter under the right hand decklid vent. If there was going to be trouble... someone in our community would have had it by now.
Slater- I have no underside mesh. Not a bad idea though. There was no mud or severe road grime in that intake cubby hole. It keeps itself clean fairly easily. NOW... skitime, I beleive, has actaully shielded his off from below. It prevents grime AND any ambient heat from the radiator pipes. That is the way to do it... When I get under there again, I will try a similar set up. He also has his pipe sheilded in the engine bay. Not flashy, but very functional.
ezromoze- I placed my intake sensor in the corner of the engine bay by the fresh air. Ideally it needs to be threaded into the pipe, but I have not done that yet. On the front valve cover, I just used a K&N valve cover filter to replace the air bypass hose that used to mount back there. That thing was WELL mounted with brackets that used to scrape my arms and fingers when I changed the plugs... Well no more! I'll take a pic of it when I show you where I mounted that AI sensor.

Would it matter where that air intake sensor is located? Could I mount it on the shortram peice close to the throttle body? or should i mount it right after the K&N by extending the wire leads?
As with the PCV Breather on the frontside valve cover. I just sawed off the end peice that pushes into gromet, and found a cheap "breather filter" from canadian tire.. Epoxied it into the chunk I sawed off, let it dry. Now I have something that I can replace the filter on for about 50c, and not worry about oil in the air intake path
And for that stupid inlet on the air tube, i just put a bolt in there with a hoseclamp to seal it off.. I cant wait to get rid of that pos hehe
It will get cooler after I wrap the crossover pipe this winter with heat wrap.
The limited warmth for the CRX comes almost entirely from the crossover pipe.
The intake air temp sensor is mounted on the fender because the air going in is almost certainly within 5 degrees of the outside air until it crosses over the crossover pipe.
If you want to insulate the CRX from the engine compartment, it can also be wrapped with heat shield material.
Now that would be the coolest air without installing a vent from your air conditioning.
hey, you could always get some sort of tube, perforate it ever inch or so, run it along the side of your intake tube, then connect it to a CO2 tank. When you want your intake cooled, open up the CO2 tank, the gas will rush out the holes along the tube, cooling, and voila! Cold Air intake.

Hey i was just curiouse if you put a matching scoop on the other side. Is that a complete ground effect package. I wand to do something with m 88 notch back and havent seen much for ground effects for it.

This shot will show you my placement of the AI sensor. There was a little hole in the corner of that area that took the sensor nicely. It keeps it tight and out of the way. Ideally you want that sensor as close to the throttle body as possible to get an accurate measurement of air temp. Makes life for your computer easier as it adjusts for rich and lean conditions. Someone asked about a hole for draining water... I have never found this necessary. Not when I took out the water seperator. Not when I used aluminum dryer ducting. Not when I had the old filter... and I drove in heavy rain. No problems. If you do it... it is probably just helping your peace of mind.... which is fine also.
I took my valve cover filter out and put it in the shot also. I think it was $15.00. Good call on the cheaper solution earlier in the thread.
oh yeah... found that stock # for the big K&N: RX-4860 It has a 6" base, 5" top, 2.5" mouth.

My car seemed to like it much much more when I drilled a hole in the intake pipe just big enough to thread the sensor in. The car was much smoother and more responsive than when I just had it sitting in the stock air box with no flow through it. I think the engine sucking the air in creating that wind cools it down a little, so its different that the regular temp in the general area.

What is everyone else doing for their air intakes on 3800SC's? I've been thinking of staying with something similar to stock Fiero but making the pipe sizes all larger and keeping the air filter box insode the engine compartment for easier access. Anyone got any input on doig it that way?
Im just kinda curious if this stuff will keep from melting with the temperature it gets under there..
