We recommend replacing hardware when doing your starter, since the bolts are aluminum and threads become stretched: Genuine BMW aluminum starter hardware set 12410392577 

Used on a wide variety of models with the BMW N52, N54, and N55 engines, including: E9X, F01/02, F07/10, E8X, E70, E60/61, F25, F30, and Z4.

Featuring silver fine wire center electrode - Superior ignition ability increases engine power!

Although these come pre-gapped we highly recommend double checking the plug gap upon receiving them and adjusting to your vehicle's individual needs.
For the N55/S55, these plugs are 2 Steps Colder, while for the N54 they are 3 Steps Colder.

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.

* One heat range colder than NGK 97506 SILZKBR8D8S

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.

*Brand new HPFP - No Core Charge!*

The High Pressure Fuel Pump (HPFP) is a point of weakness in many BMW engines and fuel systems. If this goes it will prevent your car from running or starting due to fuel starvation. Restore your fuel system's operation with high quality OEM Bosch fuel pump.

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug.

To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance!

See kit contents below for a complete list of included components.
