Installation Notes and Tips

Verify the airbox shape and the listed dimensions before installation. Compare the old filter to the new Denso 143-3444 to confirm inside diameter, outside diameter, and height match the application. For best results, inspect the airbox sealing surfaces and replace the filter during routine intake service.
