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.
Poor spark can reduce fuel economy, lower performance, and cause check engine lights. Replace your spark plugs every 60,000 miles and restore the performance you've been missing.
