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

25a. On vehicles equipped with an air temperature sensor, hold up the air temperature sensor wiring harness to the intake tube and mark the intake tube for drill point.

NOTE: On 2008 and later model year vehicles the temperature sensor is located on the driver’s side of the throttle body.

25b. On models that come equipped with temp sensors, drill a 7/8” hole in the K&N® intake tube at the drill point.

25c. Install the provided grommet into the intake tube as shown.

25d. Remove the O-ring from the air temp. sensor as shown.

25e. Install the air temp sensor into the K&N® intake tube as shown. 

26. Install the intake tube onto the throttle body with the provided hose clamp.

27. Using the provided hose clamp, secure the K&N® intake tube to the saddle bracket assembly as shown.

28. On models equipped with a air temp sensor, reconnect the electrical connection as shown.

NOTE: Due to manufacturing tolerances, it may be necessary to use the provided extension harness to connect the inlet air temperature sensor electrical connection.

29. On models that the crankcase 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.

29A. On 2008 and later model year vehicles remove the crankcase vent tube from the passenger side valve cover. Then remove the rubber elbow from the tube, and install the provided straight silicone hose. Then reinstall the crankcase vent tube so that it runs behind the throttle body .

30. Connect the modified crankcase vent hose to the K&N® intake tube as shown.

31. On models that the crankcase 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. 

32. Cut the crankcase vent tube 1” from the “T” fitting as shown.

NOTE: Cut the tube that was originally fastened to the airbox

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

34. 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. 

35. Connect the provided vent hose onto the “T” fitting, then connect the other end onto the K&N® intake tube.

36. Install the K&N® air filter onto the K&N® intake tube as shown and secure with the hose clamp.
