Ensure air cleaner inlet and ducting is not blocked or collapsed. Inspect air cleaner assembly for proper installation. Inspect filter minder on filter housing to ensure intake restriction is below Red marks. Replace filter as necessary. If necessary, use Pressure Adapter Kit (014-00761) to install a Magnehelic® gauge on the air cleaner port and measure restriction at high idle.
