18a. Install the twisted ”L” bracket with the bolt that was removed in step 18. Do not tighten bolt completely.

19. Assemble the saddle bracket assembly as shown.

20. On 2002-2007 model year vehicles, use a 8mm socket, remove the stud that retains the oil fill bracket.

21. On 2002-2007 model year vehicles, install the saddle bracket assembly with the stud that was removed in step 20.

21a. On 2008 and later model year vehicles, remove the lower A/C bracket mounting bolt shown.

21b. On 2008 and later model year vehicles, install the tube mounting bracket using the bolt removed in the previous step and the spacer provided.

22. Install the heat shield onto the factory air box studs then mount to the previously installed  brackets.

23. On models that come equipped with temp sensors, remove the air temp sensor from the resonator box as shown.

NOTE: Take care removing the temp sensor as it is very fragile.

NOTE: On 2008 and later models the air temperature sensor is located on the front of the resonator.

24. On models that come equipped with temp sensors, drill a 7/8” hole in the K&N® intake tube at the drill point.

25. Install the provided grommet into the K&N® intake tube as shown.

26. Remove the O-ring from the air temp. sensor as shown.

NOTE: Take care when handling the temp sensor as it is very fragile.

27. Install the air temp sensor into the K&N® intake tube as shown.

NOTE: Take care when handling the temp sensor as it is very fragile.

27a. On 2002-2007 model year vehicles, install the NPT fitting and NPT plug as shown.

NOTE: Plastic NPT fittings are easy to cross thread. Install the vent fitting “hand” tight, then turn it two complete turns with a wrench.

27b. On 2008 and later model year vehicles, install the NPT fitting and NPT plug as shown.

28. Install the K&N® intake tube into the silicone hose at the throttle body and align to the mounting bracket, secure the intake tube with the hose clamps provided.

29. On models equipped with an air temperature sensor, connect the harness extension into the factory connector and then connect the open end onto the air temperature sensor.

30. On models that the crank case vent hose is connected to the “T” on the drivers side of the engine, remove the factory vent hose from the “T” fitting as shown.

30a. On models that the crank case vent hose is connected to the “T” on the passengers side of the engine, remove the complete vent tube assembly from the rubber fittings in each valve cover as shown. 

30b. On models that the crank case vent hose is connected to the passenger side valve cover, remove the factory 90° coupling hose from the plastic vent tube.

NOTE: On 2008 and later model year vehicles, disconnect the crank case vent hose directly from the valve cover.

30c. Cut the crank case vent tube 1” from the “T” fitting as shown.

NOTE: Cut the tube that was originally fastened to the air box.

30d. Rotate the long side of the vent tube assembly 180° as shown.

30e. Reinstall the vent tube assembly into the rubber fittings in each valve cover so that the “T” fitting is now on the drivers side of the engine facing forward.

30f. On 2008 and later model year vehicles, cut the factory crank case vent hose 4” from the end as shown.

30g. On 2008 and later model year vehicles, insert the provided hose mender into the remaining piece of the factor vent hose and then cut the provided vent hose to 5” length connect onto the hose mender. 

31. Connect the provided vent hose onto the “T” fitting then connect the other end onto the intake tube.

32. On models with the crank case vent tube connected to the passenger side valve cover, connect the provided silicone hose onto the factory vent tube and then route the crank case tube assembly behind the throttle body as shown and connect the open end onto the K&N® intake tube.

33. On 2008 and later model year vehicles, connect the crank case vent hose assembly to the valve cover port and intake tube vent fitting as shown.

35. Align the heat shield for best clearance then tighten all the brackets.

36. Reconnect the vehicle’s negative battery cable. Double check to make sure everything is tight and properly positioned before starting the vehicle.

37. The C.A.R.B. exemption sticker, (attached), must be visible under the hood, so the emissions inspector can see it when the vehicle is required to be tested for emissions. California requires testing every two years, other states may vary. 

38. It will be necessary for all K&N® high flow intake systems to be checked periodically for realignment, clearance and tightening of all connections. Failure to follow the above instructions or proper maintenance may void warranty.
