If you need a Roush cold air intake or Hummer h2 cold air intake, or just about any other kind of high-performance aftermarket auto part, then you need to know about MotorWeb.com. This site just became authorized online dealer of Airaid, which offers some of the best aftermarket performance intake systems made. This is good news, because it enables parts buyers to have yet one more well-stocked, reasonably priced auto parts supplier online. I don't know about you, but I try never to buy parts through my dealer, and if it's something like an AFE cold air intake or an AEM cold air intake, you're better off buying the part yourself online and saving the dealer passing on his hefty markup and usually unreasonable shipping charges. And frankly, I'm all for adding a cold air intake to my car so that I can answer for myself the question of do cold air intakes increase mpg for myself. And judging from the selection of different cold air intakes that I found on AutoWeb.com, I think that answering that question won't cost me a heck of a lot, either.
