I really like my JT Intake System. As mentioned above, it really opens up the engine compartment. The huge, OEM air box takes up a LOT of room, is always in the way, and is a bear to remove and a pain to replace. These points alone make the price of the JT Intake System worth doing. And the intake, though designed to suck up ambient air which is a good thing, is pretty restrictive.
I think this JT mod does increase power and throttle response. It is not a big difference. So don't expect it to blow your socks off in the performance department.
Increased sound. It does, definitely, create more intake noise. But with the optional Pre-Filter (highly recommended), the additional throttle body volume is not only reasonable, it sounds AWESOME when you want it to!
At idle, during normal riding, and at cruise, the additional sound is not all that noticeable. Nor is it irritating. When ridden more aggressively, and at WOT, the increased volume is very noticeable. But it has a very mean, throaty growl to it. I like it! Not something that you'd want to hear all the time. But on the occasional (Go Fast) event, I think it's great! However, I find that without the noise dampening Pre-Filter, to me, it is obnoxious. It is impressive how that the piece of foam really mellows out the sounds coming from the intake.
I did one little mod to my JT Intake System mod (Modded the Mod, so to speak). I cut the velocity stacks off of the OEM air box and glued/screwed them to the top of the lower plate. This, theoretically, will smooth the airflow over the sharp edges of the lower plate, reducing turbulence and increasing the volume of air flowing into the throttle bodies. Does it actually do any good? Who knows! But I feel better about it, and enjoyed the project. I just hate leaving well enough alone! I'm the guy that fixes it, even when it's not broken.
