Does this intake work? I can't see how replacing 1 pipe will affect the engine. You still will have all the ridges in the pipe right before the TB. Its not like these intakes even draw air from a diffrent location, everything is still in the stock location. Thanks

The best part of those setups is the use of the bigger better cone filter, they allow much more air to flow through them. By ridges are you talking about the 90 degree turn tube that hooks up to the throttle body/plenum? Cause if you are, it doesn't have ridges on the inside, it is smooth.

its probably much better than the stock intake, but the k&n setup is probably the best. but for 17.99 i'd say its probably worth it
