Ok, I got me one of those 88-91 Civic CRX air intakes.
As I was thinking about it I came up with a few questions ...some related some not.
First question is has anyone removed the Fuel Vapor canister, will there be any problems if it is removed and what do you do with the hoses that are currently connected to it.

Second question is when I remove the V6 Air intake system what do you do about the case vent tube, and manifold air temp sensor coming off the air cleaner housing itself.

And third where do I connect the blue hose that came with the new intake? It looks like it connects to the chrome intake and goes ...????

Anything else I may need to know before installing this setup? All comments and suggestions are appreciated !!!!

Thanks

I wouldnt' remove the fuel dealy thingie. its there to collect fumes from the tank. You take that off and the fumes will vent to the atmosphere. Dont' know for sure but you will prob have a horrid gas smell coming from your car.

The case vent tube should go to nothing. During the recall it was plugged on the other end which should be located on the firewall back by the valvecover.

With the MAT sensor you can probably just let it dangle there as all it needs is a place to read air temp. Thats pretty much anywhere. Just let it hang on the lip there by the opening into the intake panel or drill a hole in the tube and mount it in there. I wouldnt' drill a hole though. No reason to. It will just cause turbulence in the intake. i would just mount it out of the way somewhere or stick it in the rubber "vent tube there"

That blue hose is meant to go to a vacuum line on the import cars. I would just find a way to plug that hole in the intake pipe and be done with it.

Hope this helps. how about a +??

You need to keep the vent from the front valve cover. It connects from the valve cover to the intake between the air filter and the throttle body. I have seen other people use a small K&N type filter on the valve cover that looks nice.

The piece that wil be between the TB and air filter is the chrome tube in the pic. You can't see it in the pic but the tube has a smaller tube coming of the side of it....seems like this is where you would connect the vent for the valve cover then.

I doubt your valve cover tube will line up with that hole in the chrome pipe. it could but I dont' think it does. I do hope you are able to prove me wrong though. Even if it does though I am pretty you will have to fab something up to get them to stick togethor. The valve cover tube is much larger then the hole in the intake tube if I am not mistaken.

one tip.... put a screw in the intake threw the filter housing where it connects to the piping. That filter come off easy.

Looks nice, where did you get it? Why a CRX intake instead of one of the ones made for Fieros?

Thanks,
Vin

Because they are not near as expensive and they look great....here is the same one for $20.99. Even with the outrageous shipping its still a great deal.
But do a Search on Ebay ...you may find one even cheaper. Right now there are several sources to choose from.

With mine, I just used one of those rubber vacuem caps that fit tightly over the opening. For the IAT, I replaced my old one with a new one that was the slip in type. It's hard to describe, its ribbed instead of threaded, I think it might be OEM for Cameros. Anyway, in the joint between the pipe and the throttle body I cut out a small section so that the sensor fit in tightly. I think this is better than letting it hang, as it should be a more accurate representation of the air temperature.

The ones made "For Fieros" are really warm air intakes. The CRX intake puts the filter out in the fender away from the hot engine compartment. The Fiero ones put it in side by the engine, so you're sucking up hot air instead of cold air. Defeats the purpose.

As for the blue tube, it was mentioned that the vent tube off the valve cover won't line up with the hole in the intake. So what I did was I used the blue tube to go from the intake to the valve cover vent tube. Problem solved.

Thats what I was thinking, it doesn't line up, but there is no reason you can't run a hose or tubing between the 2.

Hey zoom I also see another mod in that pic. One i did 2 weeks ago (the backup fog lights) Man that helps alot! I plan on putting 100watt bulbs in there instead of the 55 though.

Hey Blake, thanks...everyone has alot of good ideas here. I would like to see more from those who have this kit installed .
Once again thanks !!

Because the CRX intake is more so a "cold air" intake than most other aftermarket Fiero setups. The difference is that it's routed out of the engine compartment behind the quarter panel, therefore actually getting cold air coming in from the stock vent or scoop. The other styles that sit in the engine compartment don't really pick up cold air as there is warm air in the engine compartment.

Just to add to this, I moved my fuel can to the opposite side of the engine bay. There were alreadyholes in the strut tower, and I screwed directly to that..
It made for ALOT of room over there.....

Good eye !! Did you have to make some custom brackets to install them ? Any tips, and where did you route your wiring? Looks like the rear facia will have to be removed. What lights did you use ? The ones I picked up are Pilot brand backuplights that are made for trailers . The length is about 1" shorter but I think they will work out fine.
I want to do this mod so I can black out the backup lights in the tail light assembly. I think it will enhance the custom lighted FORMULA

The CRX intake sounds like a great idea, but I have a couple of questions.

1. For you guys that have this setup already, with the filter located down there, does it pick up alot of dirt/road grime?

2. How do you get at it to clean it, once installed? I know those filters don't have to be changed, but you still need to clean them, seems like it would be a pain in the butt.

TIA

I had my filter behind the big archie scoop for months and only the front side really got all that dirty. It wasn't even the fact that it filled up with sand and debris, etc, it just darkened compared to the other side. I'm guessing all that driving through pouring rain helped rinse all the heavy stuff off To clean my filter, I used a long screwdriver thru the scoop to undo the clamp, then dropped the filter out the back between the wheel liner.

I see these on ebay anywhere from $10-$150 bucks. What should I look out for when trying to pick one out? What makes some of these so expensive as compared to others, is there any real difference?

I am looking at this one right now:

Any opinions?

your wrong - the WCF intake puts the end of the filter 1/2" behind the intake vent on the driver's side of the car - which explains the length of the tube in comparison ( here I will agree with you...) to the unit from Fiero Store which does nothing more than act as a heat sink for your throttle body by simply placing the air filter where the OEM air filter canister used to sit.

Now one thing debated among these items is the fear or "theory" of sucking up water - its purely NOT going to happen. For example, the unit from WCF places the filter in the confines behind the fender liner where little to no moisture is ever seen ( unless you drive the car off a pier, in which case water getting into the engine is the least of your fears ). Now I have seen pics of the CRX tube installed ( engine bay view ), and yes, it looks DAMN good - but what I havent seen is the placement of the intake with this unit, the exact spot in which the filter is placed. Also, is there a provision on the tube to install the IAC ( and is it even the same NPT thread sive?) and a spot for the vlave cover vent tube to feed into the tube?

Overall though, I still think it's kinda sweet that a wildly mass-produced item from a honda that can come in so many variations in color and design just happens to fit the Fiero, good find to the guy that figured this out!

I was talking about the "Made for Fieros" intakes on eBay, not ones from places like WCF.

As for sucking up water, You won't get any in there unless you have the real big side scoops, and even then theres A) not enough suction to pull water all the way up to the top of the engine and B) a waterproof coating on K&N filters, so they can't pull water through.

The placement with the CRX intake puts the filter right behind the air intake vent on the drivers side of the car. Its behind the quarter panel, protected from the road by the wheel well, and pretty much isolated from the hot engine compartment.

Will the CRX intake match up with the throttle body on a 3800sc?

Anyone?

yes, with a rubber reducer pluming adapter from home depot!
