Download Step 1: Using a T20 Torx socket tip remove the screws that hold the airbox lid in place and remove the airbox lid. Step 2: Using a flat headed screwdriver, loosen the hose clamps that lead to each MAF housing. Once the hose clamps are loose disconnect the ribbed rubber hose from the MAF housing. Step 3: Disconnect the wire that leads to each MAF sensor by depressing its fixing clip and by pulling apart. Note that the fit will be snug however if too much force is necessary, then the fixing clip is not being depressed enough. Step 4: Lift out the stock air filters. Using the included tamper resistant Torx tip remove the screws that hold the MAF sensor to the MAF housing. When removing the sensor there is a rectangular rubber gasket that seals its installation. Remove this gasket and replace it with the included foam gasket. This gasket has a self-adhesive side. Be sure to peel off the adhesive backing and stick the gasket to the side of the MAF the wire plugs into. Step 5: Transfer the MAF sensor to the carbon fiber MAF housing and, using the included screws and washers, screw the assembly together. Step 6: Unwrap the included air filter and attach it to the carbon fiber inlet trumpet. At this time tighten the band clamp on the filter. Now lower the filter assembly in making sure that it slides into the OEM position. Once installed, re-fit the ribbed hose removed in Step 2 and tighten the hose clamp.
