I would highly suggest not running your header without a tune. For one you will ahve a CEL error code because when you install the header you remove the secondary o2 sensor. When you get a tune it will disable this sensor. Also your tune will be specific to your modifications.. Don't waste your money on the header if you aren't going to get a tune also.
While the tune alone will make you a little faster that is not the main thing it does contrary to what everyone thinks. It makes your car run more EFFICIENT for whatever specific parameters you want it to. For example, 93 octane, header, intake, exhaust, etc. Do yourself a favor and save up enough money for the header, an FSwerks intake, and the SCT tuner. or buy them as people post them to the Buy sell trade forum.
I'm not going to go into detail about the k&n intakes and filters.... But sell it and buy either a steeda or FSWerks cool flo.

I hope this helps.

O AND LIGHT WHEELS DO WONDERS!!!!
