How to Install SLP 2300 TVS 520 HP Supercharger on your Sierra

The following section will guide you through the disassembly of the stock components. Special care should be taken to label fasteners and parts that are taken off during this procedure since many will be reused:

1. Cover both fenders with fender covers to protect the vehicle finish.

2. Disconnect the (-) negative & ( ) positive connections to the battery.

3. Lift up on the front of the engine cover and pull it towards you to remove it from the engine bay.

4. Loosen the worm drive clamp that holds the clean air tube to the MAF (mass airflow) sensor and the clamp that holds the clean air tube to the throttle body. Remove the PCV (positive crankcase ventilation) line from the front of the passenger side valve cover. Remove clean air tube from vehicle.

5. Use a 15mm socket to rotate the tensioner clockwise and remove the belt from engine.

6. Disconnect the alternator harness and the B cable from the alternator. Remove the alternator from the engine.

7. Disconnect the MAP (manifold absolute pressure) sensor, ETC (electronic throttle control), VMV (vapor management valve also known as EVAP solenoid) and the fuel injectors.

8. Use a 10mm socket to remove the 3 bolts and 1 nut fastening the harness retention pieces to the intake manifold.

9. Remove the PCV line from the top of the intake manifold and the rear of the driver side valve cover.

10. Disconnect the fuel line from the driver side fuel rail and both VMV lines from the VMV.

11. Disconnect the brake booster hose at the fitting on the brake booster.

12. Loosen and remove the (10) M6 bolts that fasten the intake to the cylinder heads using an 8mm socket.

13. Remove the intake manifold and clean the intake mounting surfaces. Put tape over the intake ports to prevent debris from entering the engine. CHECK THE TYPE OF VALLEY COVER PLATE YOU HAVE AT THIS TIME AS DESCRIBED ON PAGE 4 ABOVE

14. Remove the throttle body, the 2 (two) throttle body-mounting studs and throttle body gasket from the stock intake manifold (a new gasket is supplied, so you may discard the old one)

15. Remove the fuel rail and set aside for use later.

16. Drain the coolant. Remove the upper radiator hose on the waterpump and cut 1.5” off of the end. Rotate the clamp so it will not interfere with the FEAD bracket installed later. Refill the coolant.

The following section will guide you through the required modifications of existing components and build up of the assemblies used to complete the installation.

AIR BOX INSTALLATION

1. Remove the entire stock airbox as one piece. It is only held in by 3 rubber pins. Pull up and out with some force to remove the stock box from the truck.

2. Unscrew the factory MAF sensor and remove it from the airbox (screw size is a standard T15 Torx). Set it aside in a safe place and be VERY CAREFUL removing as it is very delicate.

3. Next remove the four bolts in the black plate that was under the stock airbox, as well as the black plate.

4. Next, insert the factory MAF sensor into the airbox MAF tube included and thread in the factory screws.

5. Insert one of the two rubber inlet tube adaptors onto the airbox, and then proceed to insert the wider end of the airbox adaptor into the airbox. Make sure the airbox adaptor sits concentrically in the hole and the MAF is facing up as in the below picture. Proceed to tighten the worm drive clamp.

6. Next place SLP’s new cold air box in place with the large square opening in the box facing the fender.

7. Only three of the bolts will be reused to hold the SLP airbox in place. Tighten all three bolts to secure the box.

8. Next install the SLP high flow filter. The filter is a tight fit when installing it into the box, so the following steps must be taken to get the filter in the box with ease. First, position the filter so that the entire open end of the filter is under the mounting stub on the inside of the box. Push the filter down and in, under the stub. The filter will now be completely in the box under the mounting stub. Next, slide the filter to the fender side of the box so that the outlet of the filter can slide onto the mounting stub inside the box. Slide the filter all the way onto the stub and tighten the worm drive clamp.

9. Place the SLP cover onto the air filter housing and push the screw plugs into the housing. Insert and tighten the four plastic screws into the screw plugs to secure the lid to the air filter housing.

10. Next reconnect the MAF wire harness to the MAF.

11. Install the provided induction tube, tighten all clamps, and install the supplied PCV hose with clamps onto both the tube and the nipple on the PS valve cover.

12. FOLLOW INSTRUCTIONS included in the “INTUNE” Handheld Programmer before starting vehicle as engine damage will result and you WILL VOID your warranty.
