my kkm seems to work fine,especially at high rpm's..i've only had it on for a couple weeks,but it works great...i noticed a smoother idle,and tons better throttle response...also the engine seems to run smoother all the way to redline...but like i said the k+n that was on there was torn around the mesh,but i am highly pleased with the performance of the kkm...i would highly reccomend it for the svt...
