Hopefully I will be proven wrong by great gains verified on a dyno but...
so that just replaces the tube and the filter? I fail to see where any gains can be had (assuming the ECU didn't mess things up, which it does anyway)
Surely a metal pipe is more prone to heat soak than the oem plastic one, and as already seen with the K&N and Nismo drop in filters.... no gains to be had anywhere I'm afraid.
Price is as well.
I see no future for that mod I'm afraid (might as well get a Typhoon, cheaper, better presentation on the engine bay and at least you have a nice sound which you won't get if you keep the stock airbox!)
Sorry Andy if I ruined your sales pitch but what needs saying, must be said
