REMOVING THE STOCK AIR BOX (skip if already removed)

Step 1: disconnect the ECU fuse in the main fuse box to reset the ecu.



Step 2: heres your engine bay with the stock box:



Remove the two screws that hold the stock box in place and loosen the two clamps on the stock box hose. The screw locations are pointed out for u.

Here is a close up of the second screw.



once those are removed, unclip the MAF and pull the stock box out. Remove the ECU tube as well.

Plug up the butterfly valve stem with the supplied vinyl cap like so



Step 3: use the long weirdly bent hose to relocate the Vacuum Switching Valve for Canister Closed Valve to the little bracket that holds the small fuse box next to the the driver side headlight. Attach the supplied breather filter to the end of the actuator.



step 4: Remove stock bumper

Step 5: Cut a small portion of the driver side wheel well plastics to allow room for the pipe to go thru.



Step 6: Use the coupler with sleeve to attach the two pipes together. make sure you push the pipes all the way in till they meet each other. Install the MAFS into the TPR intake



Step 7: Install the remaining coupler on the throttle body and maneuver the pipe in the engine bay. Stick the car in 5th and make sure the piping clears the linkage and lines up with the mounting bracket hole. once everything is clear tighten the bracket down and the throttle body coupler.






Step 8: Install the filter on the pipe



Step 9: Plug in the ECU fuse and put on your font bumper

Start the car and let it idle for a couple minutes then take it around the block a couple times revving thru out the entire RPM band. full ecu adapting should occur after about 50 miles.
