Don't waste your money on a CAI. They do nothing.

I wouldn't bother with a drop in filter. If leaving the intake stock, stick with paper. Their CAI are good. Whether or not you'll get a check engine light or not depends if your ecu can adjust to the better airflow or not. If it does go off, you will need to have it dyno tuned or tuned from a handheld.

What's the difference between paper and theirs?

>>17337384
Theirs is cotton/fabric filter with an oil additive.

Your engine is going to suck in the same amount of air regardless if its paper or fabric.

Why would he need it tuned? The MAF should just compensate for increased airflow

>>17337410
Most MAF's will compensate when airflow is less than OEM specified, but not above that.

Just kill yourself and be done with it

Are their short rams good? Considering one for a low end torque boost for my Corolla.

>>17337384
Paper traps more. The only way the drop in gives gains using the same surface area as the paper is by letting more through, which means it doesn't filter as well.
>>17337410
The factory tune has boundaries, anywhere outside the boundaries it sets off the light. A tuner can reset the boundaries and adjust the engine accordingly.

The cone style has a larger surface area so it can filter just as well and still let in more air. Normal operation you hardly ever do need a filter. If you're driving on dirt roads or it's Dusty in your area all the time then yes I'd say consider sticking with stock.
