Filters and "cold air intake" kits are not going to do anything. Their a total scam. Adding measurable useful performance requires real engine modifications and accompanying exhaust work too. None of it is cheap either. Fancy spark plugs, fancy coil packs, and fancy spark plugs don't do jack either. There is no such thing as inexpensive horsepower no matter what the colorful packaging says.

We don't hate them. We just know enough to realize they're a marketing joke. Trying to inform people of reality before they waste their money on a shiny useless tube then gets us labeled as haters by the CAI fanboys.
