Installation steps

Preparation: Turn off the ignition and disconnect the negative battery cable. Allow the vehicle to sit for 5 minutes to drain any remaining charge. Ensure the emergency brake is engaged.

Removal: Remove the 4 plastic clips holding the intake duct to the plastic shroud. Loosen the clamps on the stock intake tube, remove the small hose clamp from the evap system, and remove the two bolts on the adapter section. Release the intake duct from the shroud and the rubber connection. Remove the MAF sensor from the factory airbox, taking care not to damage it. Remove the airbox lid, filter, and the front bolts with dampeners. It is recommended to remove the ECU for better access to the final side bolt.

Assembly: Install the rubber grommet from the factory standoff into the bottom of the PRL airbox. Assemble the PRL airbox by inserting the machined MAF to filter adapter into the filter and tightening the hose clamp. Secure the MAF housing onto the adapter using the supplied M5x12mm bolts (torque to 11.2 ft/lbs). Secure the side cover using the supplied bolts (torque to 24 in/lb). Install the brackets onto the airbox using the factory rubber dampeners.

Final Installation: Place the MAF sensor into the PRL MAF housing and secure it with the supplied bolts. Install the PRL silicone hose in place of the factory hose, ensuring all clamps are installed before the hose. Connect the vacuum lines to the plastic evap adapter and tighten the clamps. Reinstall the factory rubber piece for the duct and the factory intake duct. Double-check all connections and bolts before starting the vehicle.

Maintenance and filter cleaning

Visually inspect the air filter at every oil change. Clean the filter element whenever the screen is no longer visible or every 30,000 miles, whichever comes first. Use the #2801 filter cleaning & recharge kit for maintenance.

Filter Recharging Process:

1. Pre-Cleaning: Tap the filter or blow with air to remove excess dirt.
2. Apply Cleaner: Spray the filter with the cleaner kit and allow it to soak for 15 minutes.
3. Rinse: Rinse the filter with warm water, from the clean side to the dirty side.
4. Drying: Allow the filter to air dry. Avoid heat to prevent shrinking the cotton.
5. Apply Oil: Re-oil the filter using 1 spray per 2 square inches of filter. Do not over-oil.
