Subaru gave you a great base to start with: Even their lowliest vehicles have some neat sporting characteristics. But it's up to you to finish the job and turn your little Subie into a rocketship. Step one: Subaru cold air intake. A Subaru cold air intake bolts to the throttle body in place of the plastic stock tubing and replaces the entire air filter and intake duct. You'll notice your Subaru cold air intake has fewer sharp curves and extends outside the engine bay. That's so the Subaru cold air intake can flow air more efficiently and grab cooler air away from all the hot engine components. If you're thinking about picking up a Subaru WRX cold air intake or Subaru Impreza cold air intake, we can't encourage you strongly enough. These cars are a blast to drive, and even more so when you have a Subaru cold air intake fitted to them. Turbo or normally-aspirated, the flat-four engine design just seems to relish the additional dense intake charge it gets from a Subaru cold air intake. So take it from us: If you put a Subaru cold air intake on your WRX or Impreza, or even your Forester or Outback, your Subaru will reward you handsomely. That Subaru cold air intake doesn't need to cost an arm and a leg either. Not when you buy your Subaru cold air intake from us, anyway. We always guarantee the lowest prices on our huge selection of Subaru cold air intake products, and we'll ship your order the same day we get it so you don't have to wait for the fun to begin.
