DO NOT GET K&N Air Filters!!!!!!!! They say they have excellent air filters and they do provide great airflow, but with all that airflow you've got to be sacrificing something, and what do you think that is? Well its filtration, it sucks up all that air and debris and gets thrown down into the block and valves and causes boreing (little holes and imperfections) thus cutting the life of your engine short. Also they say that the filter has to be OILED , well common sense can tell you that oil atracts things, and what should somebody be worried about when dealing with air filters..........hmm i wonder, so ironically you're attracting dirt to you filter by using the recharging system that you "HAVE" to buy from them. So what sense does it make to pay big bucks for something that isn't going to work and when you clean it all your doing is letting it get dirty all over again. take it for what its worth.

 

but other than that, I like their products.

 

Increased airflow comes at a cost. In this case, it is less filtered air.

It is a good product...if you own a race car (no, no amount of modding will make a Scion a true race car) and run it on a track where 2/10's of a second mean something. For a daily driver, they are just not worth the damage they cause.

^^ yup. Just ask STi owners, they figured out a long time ago that K&N just wasn't worth it. Maybe it provides higher flow, but it really didn't do all that much filtering.

You might as well just take off the air filter completely. But hey, its not my engine
