Note: If interference is encountered between the air filter
lid plastic ribs and mounting hardware or fittings on the
compressor or rear spacer clamp fastener, then trim the
necessary plastic ribs to allow easier installation or
removal of the air filter lid. Do not cut through the sealing
edge that sits against the air filter.
□ Add the MAF extension cable to the mass flow sensor wire and
reconnect to the sensor. If the wire is too tight reroute where it
attaches at front of the truck (under filter box) to get more slack.
