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.
Swap out your worn out old factory spark plugs for NGK's OE replacement version the NGK 97506! Note that BMW Spark plugs require a special 12 point 14mm thin walled socket. We have several options available in our catalog that will help you get your spark plugs changed. The BMW part number for the tool is 83300495560, but we recommend the Schwaben brand T#373727 that won't cost you an arm and a leg.

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.

Poor idle, low fuel efficiency, and engine misfire codes are all symptoms of worn spark plugs. Replace yours with quality factory parts to get your engine running as well as possible. If you are replacing any aspect of your ignition system, it's best to replace all serviceable components. By doing so, your ignition system will work in better harmony, freeing up hidden horsepower and raising fuel economy. Skim the ECS Tuning ignition area under your model for spark plugs, wires, coil packs and more to get your vehicle into top shape.
