High-performance spark plugs are recommended only when used with highly-tuned engines that see a lot of high-RPM work (TMS head, cams, etc).
Over time spark plugs become contaminated, worn, and "fouled out". This can cause a weak or missing spark leading to issues with fuel efficiency, misfires, check engine codes, and poor idle or even direct damage to your catalytic converter.
As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!
