NGK Racing Spark Plug Box of 4 (R0045Q-10)

NGK is well-known for making reliable ignition components, and their Racing spark plugs are built to handle the toughest conditions you can throw at them. If you're working on your 2000 Aprilia RSV Mille SP for track days or racing, these plugs are designed to keep up. They feature special center electrode designs that help ensure they last and fire consistently, even under heavy load.

These NGK Racing plugs come in a variety of heat ranges, and this particular model, the R0045Q-10, is configured for demanding racing applications. The trivalent metal plating on the outside helps prevent corrosion and makes them easier to install and remove later, which is always a plus when you're working on a performance machine. The pure alumina silicate ceramic insulator is strong and transfers heat effectively, while the special nose configurations are meant to improve throttle response. Plus, the copper core helps pull heat away from the combustion chamber, and triple seals are there to prevent any leaks.
