Went through a couple of intakes to figure it out, had to do some of my own work with the 90s and sensor input. Wondering if people are interested in buying something like this. Wondering what people think of it. I do feel a slight increase believe through the higher rpm's. I don't know if its the sound messing with me or what. I have a magnaflow exhaust with the sprint booster and this tank that I just filled up was 92 un-oxygenated, I cut the ports out from behind the grille and I feel like I can feel a difference. That box is definitely holding back some horsepower like X said when he had his dynoed with and without the engine cover on. Whether or not I'm getting true cold air isn't the factor. If you have ever driver for an hour sometimes a half and hour and felt the engine cover or even the tubes they are hotter then hell. This past week when I got home ready to work on this I couldn't even hang onto the engine cover it was so hot on the underside. Anyway let me know what you think...
