Last Station is kinda expensive, and right now there are few actual dyno tests out there from well know manufacturers, and some less well know, that show how these perform. Also consider the Fujita cold air intake, the new AEM cold air that's being developed (if not already available), and the T1R prototype that's being developed by the folks at A&J Racing. I'm still waiting and studying the various options out right now. None seem satisfactory for me: too expensive, not aplicable for A/T, not offered in anodized blue, and so on... I'm very picky
