like i said i put them in everything and my dd'* see alot of miles. ive never even had to clean a maf on a vehicle a bought new or almost new. the only maf i had to clean was in my yukon where someone had put the k&n in before i got it. you just dont go crazy with the oil and its fine. i usually let them dry over night before putting it back in the car.
i dont like cai'* for a few reasons, one is i the only time i had to replace a maf is when my firebird was fuel injected i put one on it and it let the rain in and eventually destroyed the maf. and even if it does what is supposed to it is only beneficial at high rpm so unless you are racing it why bother. they are stupid expensive for not much benefit for a normal car.
