i have installed a short ram intake into my corolla, but when i accelerate it bogs and does not jump into gear correctly, it slowly accelerates.
and also my check engine light goes on as well.

what do i need to do to make it work correctly?

is your MAF sensor hooked up correctly? or your vacuum lines. double check and provide pics if you can

well i took it out so it isnt installed right now. so pic unavailable.
but i was talking with someone else and i think i figured it out.

the intake i have doesnt have the correct MAF sensor fittings.
it installs correct and everything but the fittings are a lil diff.

so i just bought a new one and am going to install it when i get it and go from there.

The problem is that no one makes a CAI for the 8-gen Corolla. The only one on the market (other than the nonames on eBay) is made by Injen, and it is a short-ram.

The problem with the short-rams is that the filter sits way too close to the exhaust manifold so it just sucks in hot air, completely defeating the purpose of the intake.

I put an Injen on mine and took it for a test drive. The performance was so bad that I took it off two hours later. I put in a K&N filter in the stock air box and it has done more for performance than the intake ever did.

My advice is to skip the intake altogether.

All RAI on the 8th gen Corollas are worthless and make the car lose power due to heat soak from the header. btw, the RAI and CAI differences are pretty much a myth. It's all marketing tactics for AEM, Injen, etc. Properly designed RAI and CAI all have pretty much the same intake charge temperature which negates "cold air". The only difference is at a stop. When moving, power is dependent on volumetric efficiency alone. PM me for more details. :)

I agree with Cyberbilly. The best option is the just drop in a performance panel filter. K&N, Apexi, Blitz all make them. You can also remove the resonator box for more sound and more volumetric efficiency.

well i just recieved the new one i just bought today, it was listed as for a 01 or newer corolla type s, and installed perfect into my corolla with all correct MAF connections and all.

and is working great with it in, ill see how it is doing after a couple days.

What is the resonator box?

^^^ There's some tubing in the fender that runs to the airbox. That tubing has multiple chambers and tubing of different volumes and lengths that attentuate the sound coming from your intake manifold - makes things nice and quiet, also a potential source for intake restrictions.

Thanks, so it's ok to take it out like rollatuner right? No down side except a louder intake?
