Since the only reason we had to replace our million-mile-warranty K&N FIPK shown in the lead photo was that a big, ugly piece of duct tape closing off the hole we drilled for our nitrous nozzle, we dutifully ordered up the exact-same FIPK (PN 57-1518) and installed it right onto the heat shield from the older one. The K&N FIPK delivers a noticeable improvement in throttle- response on a 4.0L engine, and, compared with the restrictive factory ducting and filter, adds about 1 mpg to the fuel economy.
