For those with an LS motor in a second gen CRX, what cold air intake works for this setup? A friend of mine just bought a CRX with an LS motor and would like to add a CAI.

 

good question, i wanna know too but for a crx with a gsr motor.

 

now that you mentioned that, does anyone know what CAI's would work for an LS/VTEC with a GS-R head?

 

Just get one for a crx...it will work.

 

Would'nt the crx cai diameter be to small ? I would say go with a b series cai, I would go with a 00 si cai.

i have a ram air, 90-93 teg. fits perfect
the cai will prolly work too

 

ok lets put it this way

lsvtec, gsr, b18b, b16a, crvtec, and D series (si version) all take the same cold air intake, as long as you make sure that it is at least 2.5" mandrel bent you should be fine on a b series set up, just get one for a crx that has a 2.5" mandrel bent tube


thx

 

just buy the AEM peice for the 99-00 si coupes
fits directly in the crx bay with a b motor.

 

You forgot to mention that you need to relocate the battery.

 

well yes you may want to, or just get a smaller battery.
i did however do the relocating of my battery in the crx. but before i did a b swap

 

ok, thanks guys. My friend already relocated the battery to the rear of the car. do you guyd know which B series CAI has 2.5" piping? the 99/00 Si intake?

 

Yeah the 00 si intake will be fine.

 

aem will be coming out with their new cold air intake, the V2 which starts out much larger (4 inches) and then tapers.

Do you think that the 99-00 Si V2 will fit into an ef?

 

I am using the oem intake system from a 91 Si HB on my crvtec'd crx si and it works fine.

Yea, the 99-00 Si cai with a relocated battery is the way to do it.

 

Yeah I never said it would not work, but you want to match the cai with the throttle body the best as possible.

 

The correct b-series intake diameter is 2.75 not 2.5. 2.5 is the D-series intakes.

 

good call

 

ok you'll be FINE with a crx/ef CAI.

*If you think you motor is going to be reving like in the 8k range get the CAI for the 99 si (2.75) you will have to move battery. Fits perfect and looks great.

If you are really really seriouse about doing a B18b all motor get a ITR cai which is 3inch piping.

I have the ITR CAI for my B20

 

we are glad that u have this, but hes got an EF chassis, not a 92+ chassis.
the itr CAI will NOT work,
the best fit, and performance AVAILABLE for these types of cars with swaps is the 99-00 Si aem cai.
thank you.

 

Thats what I have been trying to say

 

Not true. AEM LS intakes actually use 2.5 inch tubing. So if you just get the CAI for the CRX, you will be fine. The 2.75 inch tubing is only used on DOHC VTEC applications (B16A, B17A, and B18C1). The only other exception is the ITR, which uses 3 inch tubing.
