Well... From what i'm hearing, on SOME high dollar air intakes ( ok one ) the filter is a restriction ( and they know this because after spending $300 on an intake, they upped the filter size and power increased, but I'm not getting into that right now ).
For me... Its about pipe size and more importantly, the over all length of the piping.
If you have a good intercooler, the air box or air filter getting head soaked in traffic is going to mean very very little since that 15 degrees or so is brought back down almost instantly the second you hit .5psi ( or before ).
But the stock piping SIZE ( in my case) is a restriction on the stock turbo, and its got to be an even bigger issue on the cyborg. The BIGGEST issue to me is still the fact the turbo's compressor blades are like 6 feet away from the area air is pulled from.
I wanted to do an experiment where I took a filter and bolted it directly to the turbo, moved the MaF to right before the throttle body and tested that. It would be pulling some pretty hot air, that's true, but it would also be cooling that air down via a big intercooler. Zero restriction, but warm air vs cool air but a ton for restriction with the stock system. Well... Not to sound like I'm trying to sell stuff for 2J, but this intake is the perfect happy medium for my dilemma. Coolest air possible, no relocating and boosting the MaF, almost no restriction, and reliable. The one down side is it will be loud, but hey... Jeep wranglers suck at EVERYTHING except offroading, and they seem to be pretty popular, this intake is PERFECT AT EVERYTHING, and only has one bad thing, lol.
Also. Yes.... Jeeps suck. I hate them. Jeeps suck. Lol.
