I have a Injen and I'm totally happy with it. Before that, I had the stillen longtube. I must admit the first run was really good but has tapered off since. I attribute this to the ECU correcting back to near stock conditions. Even with that it still pulls a lot better than the stillen. As far as the JWT that was one of my first choices but I opted for the stillen because of the closed boxes and their distance from the engine. When I get my flash done I'll post it and we can see if it gave me any more HP. Remember, I modded mine so it gets cold air directly to the filters. A complaint some people had about using hot air. All I care about is the end result, the most I can get with a NA engine. As hind sight, a intake would be my last mod and I'd just drop in some K&N's then HFC's and a complete cat back exhaust.

 

It's that price plus $9.95 for insurance.
