If you would prefer not to modify your production supercharger front cover, LPE can supply a stock GM cover for you to modify or one with the parts already installed. Read the entire instruction manual before beginning installation. Many of the stock parts will be used in reassembly. When referencing the side of the vehicle, the driver side of the vehicle is considered the left side and the passenger side of the vehicle is considered the right side of the vehicle.
1. Open the hood of the vehicle. If you have been driving the vehicle, allow the vehicle to cool down for a few hours before beginning this work. 2. Remove the connector from the mass air flow/intake air temperature (MAF/IAT) sensor electrical connector located on the end of the intake duct on the air filter box. 3. Remove the fresh air inlet positive crankcase ventilation (PCV) connector from the middle of the intake duct. 4.
. Loosen the band clamp on the factory air cleaner housing using a flat head screwdriver or an 8 mm hex bit Allen socket. 6. Carefully remove the intake duct, be careful not to let dirt or debris enter the intake duct during the installation. Steps 7-22 are for disassembling the airbox to modify the bottom part of the air filter houseing, which will reduce inlet restriction. 7. Using a T-25 Torx tool, remove the three (3) Torx bolts from the top portion of the air filter housing.
9. The location of the third bolt is directly behind the driver front headlight assembly. 10. Carefully remove top of air filter housing. 11. Using a 10 mm socket, remove the air filter housing bracket bolt located on the driver side strut tower. 12. Carefully remove the bottom portion of the air filter housing by pulling up and away from the fender from the location shown. Page 5.
13. We are now going to modify the factory airbox. Any kind of cut-off tool or die grinder will work for this portion of the install. 14. Using a flathead screwdriver or small pry bar, pry away the air inlet from the bottom of the factory air cleaner housing. 15. Use the next 5 pictures as a reference. Use a silver marker and mark out the locations on the airbox to cut. This is the front of the factory airbox. 16. (Left side of factory airbox) Page 6.

21. Re-install your modified bottom portion of your air filter housing. Reinstall your stock air filter or install the K&N replacement filter. NOTE: LPE recommends the use of a K&N air filter (part # 33-2411). 22. Install the top portion of your air filter box. Make sure to plug in the MAF sensor after bolting down the housing bolts. 23. Install the barbed end of the supplied 45 degree plastic fitting [part # 25862741] into the fitting on the hump hose. 24.
25. Mount the front coupler on the throttle body and tighten down the band clamp. Make sure to position the inlet as indicated to the left and reconnect your PCV hose. 26. Install the other coupler in the kit to the air filter housing and tighten down the band clamp on housing. 27. Loosen both band clamps and put them on both couplers. Gently work the LPE provided elbow into both couplers. Move each band clamp towards the elbow and tighten when it reaches the edge of the coupler as shown.
