Bmc race air filter. Excellent condition.
This is the high flow version not recommended as a stock replacement.
Some people cuss the hello out of it, but mine worked beautifully after many hours of tweaking and worn out bowl screws.
I used the factory pro kit, HrC slide mod, Ducati velocity stacks, degreed cams, Kerker exhaust, modded airbox, and advanced ign. Timing.
You have a built engine there is extra power potential with the increased flow.
I'm trying different intake set up, selling this recoup cost.
45.00 including shipping.
