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.

When it comes time to change your spark plugs, you may wonder about colder stepped spark plugs as many others have. Colder spark plugs work by pulling more heat out of the engine's cylinders (making them "colder") and dissipating it into the engine's head, which is then cooled by the cooling system. Depending on how you have your engine built, these could be a great addition! Colder plugs can help prevent engine knock and prevent the tip of the spark plug from melting or misfiring. There are two rules that most people tend to go by when deciding on which spark plugs to buy: The first rule of thumb is that with every 100 horsepower added, you should run spark plugs that are a step colder than your stock plugs. This is generally accepted across the motorsports community but unfortunately isn't always the most accurate measurement of when you will need colder plugs. The second rule is to go a step colder any time you massively alter cylinder temperatures by adding forced induction to an NA engine, by increasing compression ratio, after altering timing in a major way, or by changing fuel types to something with a higher octane rating such as racing fuel. Adding spark plugs that are a step colder outside of these conditions, with no real change to the engine, can actually hurt more than help by leading to spark plugs fouling quicker than normal and by making the car harder to start in cold weather conditions. We suggest talking to your engine builder or tuner before making the change, or you can call our Turner Motorsport sales staff to discuss what modifications have been made to your vehicle and see if these plugs are right for you!

Dinan Iridium Spark Plugs are an excellent upgrade for tuned, and even stock engines. Our spark plugs are made from Iridium - one of the strongest materials available. They last longer than other materials with higher melting points, run cooler, resist preignition, and even require less voltage to produce a strong spark. The iridium electrode with its copper core is harder and stronger than other materials, can dissipate heat more easily, and is better protected from melting, cracking, and other limitations found with standard plugs. Dinan spark plugs are great for high boost, high cylinder pressure, high cylinder temperatures, and high-power situations, and they pair nicely with a set of Dinan ignition coils, where applicable. However, they are not only for tuned and higher output vehicles that may benefit from a plug cooler than the factory heat range - they also are applicable to non-tuned / stock vehicles as well! The D640-0003 spark plug applies to the following engines: B48 TU B58 TU2 (Gen 2 B48 Gen 3 B58)
