i just wanna add something to this thread to help alot of people understand what cold air intakes and free-flowing exhausts do.

when you add these systems to your car or (any car) all your doing is freeing up the "PUMPING" loss from the restrictive OEM stuff. thats why the power gains aren't so great, but you do get the response when you tap the gas.

just thing of yourself trying to run a race with a gas mask on...you'll breath clean air, but your sucking really hard to get that air. run that same race with nothing on, you'll breath alot easier, but you won't run like superman! CAMS make the biggest impact on engines, but so far i don't see anybody making cams for our cars[:@]
