Yes and NO! Just what you wanted to hear I am sure. Somewhere TRD has done a dyno test on the CAI and it's supposed to give you the additional 15 hp. The downside is that most of this power is at WOT or at least in the upper RPM range. Under average normal driving conditions it doesn't do much at all. I would expect to see a little better gas mileage with a less restrictive intake, but that will likely be more than offset by you punching it more just to hear the engine growl. It's a fun noisemaker which provides the illusion of a power increase and best of all, it's expensive!:cheers:Does the TRD CAI actually increase performance? Is it noticable?
