Oil Impregnated Air Filter Maintenance On my K&N, the instructions say that frequent cleaning is not necessary. When you cannot see the “red” it’s time to clean.

Adding cheap, easy horsepower By James Prunty The two choke points on the LS2 are the intake and exhaust manifolds. Cast iron exhaust manifolds have improved over the years, but still substantially restrict horsepower to the rear wheels.
