Intakes are VERY important that you get the right ones.
I would NEVER get a cheap eBay one, one from an unknown off-brand, or K&N (or any other oiled filter). I would only get a good, dry type filter from a name brand.
My choice would be the Apexi Power Intake. Its about 55 bucks for just the filter. Fab your own piping.

Also, get one that sits in your bumper (with a hydrosock to assure water won't get in), not the kind that sit in your engine bay. This will assure only cold air gets in and not hot air.

K&N has been proven not to filter or flow all that well, and there are MANY DOCUMENTED CASES of oil from the filters ruining the MAF. Some of this is because of owners over-oiling their filters, other times it is over oiled from the factory. I would stay away from them.
