Just to add to them two posts, imagine how much money went into the R&D of the Toyota air box and filter system, then imagine how much R&D went into a K&N, Blitz or HKS induction system.
Thats not to say that induction kits don't have their place, its just the advantages on a BPU car are not all they are hyped up to be. Remember heat is a killer to a forced induction engine.
