Steps
- Open the air box and remove the old filter
Loosen the intake-hose clamps and detach the hose from the air box. Release the housing clips, lift the cover, and remove the old filter without dropping debris into the intake.
- Install the new filter
Place the replacement filter in the housing with its sealing edge seated evenly. Close the air-box cover, engage its clips, reconnect the intake hose, and tighten the clamps so the joint is secure.
- Check the intake seal
Confirm the filter cover is fully latched and the hose is seated at both ends. Start the engine and listen for an intake leak or loose housing vibration.
Check your vehicle’s repair manual for exact specifications and fit.
