• The air filter is located on the driver's side; the filter element itself is a large, black, cylindrical box.
• 4 metal clips (retainers) lock the air filter into place, as well as two barbed prongs on the underside.
• Un-clip the metal retainers and move the intake tubes in front of and behind the filter out of the way. This may require some finesse, since the filter has hooks in the front and rear that create a positive seal between the filter and tubing (reference your new filter to see how it is held in place).
• Once the intake tubes are pushed out of the way (you'll only get about 1/4-1/2 an inch of clearance), pop the filter loose by tugging straight up. A pair of barbed prongs secure it to the bottom mount; they should release with a firm pull. If that doesn't work, rock the filter side to side while pulling upwards.
• Install the new filter in reverse order, making sure the barbs snap into place. Notice how the loops on the front and rear of the air filter need to be lined up with the corresponding grooves on the intake tubing. Failure to properly line these up will result in a poor seal and may allow your truck to pull in unfiltered air.
• Lock the retaining clips. The tubing and filter should line up properly if they were installed properly. A flashlight will help you double check your work.
