This spark plug's fine-wire iridium core and platinum ground electrodes give the sharpest possible spark focus for maximum performance. The special heat-active alloy allows electrodes to attain optimal temperature rapidly and maintains stable operating temperature under all load circumstances in passenger cars, light trucks, and power sports applications. V-timed BRP Copper Plus plugs have a V-shaped firing end that improves the plug's ignitability. They have a V-shaped ground electrode for greater spark focus and a small wire center electrode for precision ignition. Their long-lasting, one-of-a-kind SAC-9 semiconductor resistor provides maximum EMI and RFI suppression, allowing your car to perform at its best. Key Features: The platinum ground and fine-wire Iridium core electrode provide optimum life. Allows electrodes to quickly reach their optimal temperature and maintain it under all engine loads. Engine performance is the best, regardless of the engine type or ignition system. With a more concentrated spark and better throttle response. Maximum EMI and RFI suppression is provided using the BRP proprietary SAC-9 semi-conductor resistor. Product Details: SKU: 5007597-PK Weight: 0.12 LBS Brand: BRP
