I chose the JWT intake because it came with a velocity stack, like the Stillen unit, but it was $40 less. As far as I can tell the only difference is that the JWT does not come with an official K&N air filter. Instead it comes with a filter that looks exaclty the same, but has no company logo on it.
Installation was easy even though the instructions were rather vague. The only difficulties I had were:
1. Removing the stock air box was a pain.
2. The included mounting bracket had to be bent to make it fit.
I noticed a siginificant increase in high-end power, and a small decrease in low-end power. The car is also quite a bit louder at WOT, but at "normal" RPMs the volume increase is not very noticible.
The only problem I have had is a small whistle when I step on the gas. I suspect that this is from a small intake leak, but I am too lazy to hunt it down.
