ETS Black Air Intake Kit w/K&N Filter for 2003-06 Mitsubishi Evolution 8 9 The ETS Air Intake Kit is a great modification for EVOs running the stock MAF. This kit eliminates the restrictive stock rubber intake pipe and filter, and replaces them with a high flowing 3" intake tube, contoured velocity stack with 4.5" filter inlet and genuine K+N air filter. With this bend gone and with a large radius 3" inlet, the air now has a smooth, direct path into the turbocharger. Typical power gains are 10-20hp depending upon boost level and engine modifications. This kit works with stock and aftermarket intercooler piping, and will work with all aftermarket BOV's that fit the stock intake tube.
