Any good? i see there pretty much inexspensive (109)
anyone know anything about them?

Dont even bother with that, its basically an overpriced warm air intake setup, which you could put together for like 30 bucks. Or you could do what me and chris (nismoser) did, we had our local muffler shop bend cold air piping for us to go from the maf into the fender and we got K&N filters at the end. It sounds great and i can definately feel it pull harder then my previous warm air setup. all in all, we spent 45 bucks, 15 for the piping and 30 for the filter and maf adapter. Hope this helps!!

OBX and high performance should not be used in the same sentence... like nismo says you can make one that will give you the same gains for a lot less... or spend a little more for a real intake
