Please check notes in each part listing to ensure the Spark Plug is correct for your 2003 YAMAHA YZF-R1 with a 998cc engine. AUTOLITE, CHAMPION, DENSO, & NGK are competing brands, and each brand's Spark Plug may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Spark Plug fits only certain 2003 YAMAHA YZF-R1 models.

Clicking a "More Info" link will display a picture and/or other details about that Spark Plug in a separate window (you may need to turn off your pop-up-blocking software for this to work).

You may use your browser's Back button or click "Find More Parts" to find more Ignition parts, other YAMAHA YZF-R1 parts or parts for a different vehicle.
