I just dont get all this hype about induction kits, the air amount can not be changed because the engine will only draw x ammount on its natural cycle, if you have a good filter you may notice a difference but only a tiny one. A jobby filter will choke it. As long as you have a good filter pointing at some fresh air away from heat things should be dandy. The gains are too low and inconclusive for me to give a jobby about spending silly money on an induction kit for a road car.
There is a lot to be said for the ebay cheapy ones, they polish up well and they sound fooking great, better than stock one.
This is an age old topic and always has the same outcome. I will stick to my cheap stuff. My ludes have always performed very well with them, infact I will try and get a dyno done this year with a stock one and an ebay one just for fun at the pod this year.
