NOTE: For the N54, these plugs are 2 Steps Colder, while for the N55 they are only 1 Step Colder. 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!

Symptoms of a necessary head gasket replacement may include: oil and coolant mixture found in your engine (also referred to as "milkshake"), misfires from a cylinder losing compression, or just if the cylinder head is removed from the vehicle. This multi-layer steel head gasket has raised printed seals, for improved sealing of fluid passages. Purchase head bolts and related attachment hardware and gaskets separately.

The guide rails in your timing set keep everything tracking properly. Because it is made out of a plastic-like material, years of abrasion can wear parts of it away. This can cause the chain can to become slightly loose and cause a chain 'slap' or rattle noise. Replace your damaged timing chain tensioner and guide rails to keep timing chain noise to a minimum. Located on the outside of the timing chain guide that keeps tension on the chain.
