I'm not taking sides here but there is very little difference in power from an intake filter
I have them on my car, motorcycles, jet skis and snowmobile but really just because of the clean & reuse factor. There is a sound difference but let be real here performace - not - though I like to think there is .
Another thing that gets me and I find it with my car club too is the use of aluminum on the intake systems. OK it looks pretty and great to show but doesn't aluminum absorb heat quickly ? So your putting in transfer engine bay heat into the intake ? There is a "Cool intake system" on the market that has an insulated intake tube to the a external intake location which allows cooler air to the motor - now that might be worth taking a look into - but it might be a "scam" deal too.
