Turner Motorsport insists on Genuine BMW or Bosch OEM or NGK OEM spark plugs in all of our work and maintenance packages. Bosch and NGK are original suppliers to BMW for spark plugs and the ignition system is set up to use these plugs. To keep the engine running at its best, and get the most from your performance upgrades, we only recommend direct replacement spark plugs. We also sell helpful tools and accessories for changing out spark plugs. Some engines require special tools for replacing spark plugs.
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. This OEM spark plug made by Bosch will restore OE spark plug operation and function, returning lost power and fuel efficiency.
