BMW Maintenance & Tune-Up Parts for BMW X Series E84 (2013-2015)

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.

Brisk Silver Racing Spark Plugs are the best solution for high performance and racing engines. Silver Spark Plugs provide many unique and beneficial characteristics, Silver is taking spark plug technology to a whole new level, here are many reasons why our Brisk Silver Racing Spark Plugs are beneficial for your engines performance. Silver is the best conductor of any metal! It conducts 560% more electricity & 481% more heat than Platinum, and 276% more electricity & 177% more heat than Iridium.

Silver spark plug electrodes transfer electricity & heat better than any other spark plug material resulting in the most powerful spark! This is beneficial for a full complete combustion of the available fuel and air in the combustion chamber, combustion efficiency creates horsepower gains.

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.

Using proprietary blends of base oils and the latest additive technology, this full synthetic oil will ensure smooth running gasoline and diesel engines in both high and low temperatures.

New generation Molygen engine oil allows you to easily identify oil leaks with the included UV flashlight - BMWs are notorious for oil leaks, and this allows you to work towards solving this problem. Additionally, Molygen is a fully synthetic oil designed to provide the highest amount of engine protection as well as fuel savings and reduced oil consumption possible. 

Choose the level of Liqui Moly Oil Service your BMW deserves: 

• Liqui Moly Bronze service involves switching to Liqui Moly oil without the introduction of additives.
• Liqui Moly Silver service includes a Pro-Line Engine Flush to remove sludge and carbon buildup from the oil circulation system.
• Liqui Moly Gold service includes Silver service and Jectron Fuel Injection System Cleaner. This cleans your injectors and maintains your fuel system to improves engine performance and efficiency.
• Liqui Moly Platinum service includes Gold service and Cera Tec Oil Additive. This prevents wear and reduces friction to improve engine performance and efficiency.

Below you can add new drain plug and crush washer, along with your choice of oil filter.

This kit also features many Popular Service Tools that make your life easier when working on your BMW:

• Turner Motorsport Magnetic Fender Cover
• Schwaben 6.5L Fluid Extractor
• Schwaben 14mm/17mm Service Wrench
• Schwaben Professional BMW/MINI Scan Tool

Have you ever been bent over your engine bay for a few hours and noticed that your belt scratched your fender? We've got you covered with the Turner Motorsport Magnetic Fender Cover. We also offer a myriad of Schwaben tools. Schwaben's Professional Scan Tool vastly simplifies diagnosing your BMW. This scan tool offers OE-level diagnostics for over 25 years of models, also allowing you to access common service features like resetting your oil service light, installing a new battery, throttle body adjustment, DPF regeneration, and more. The Schwaben Fluid extractor allows you displace 6.5L of fluid without making a mess of your workspace. Lastly, we've found that the 14mm/17mm service wrench allows you to service most of your vehicle with just one tool - one of the biggest hangups with working on a vehicle is losing your tools. Save yourself time looking for multiple different tools across your garage by owning one that does it all.

Poor idle, low fuel efficiency, and engine misfire codes are all symptoms of worn spark plugs. Replace yours with quality factory direct parts to get your engine running as well as possible.

These plugs from BMW are the solution for all of these problems. Over the years, the electrode wears away on spark plugs, causing too large of a gap and weak spark. Additionally, excess carbon can build up and bridge the gap to negatively effect performance. Replace yours with these factory correct units to regain your power, fuel efficiency, and smooth a poor idle.

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.

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.

Removing the cowl saves weight, simplifies maintenance, and lowers underhood temps. Keep things clean and free of debris with these BMW cowl filters. Dry filters will require little to no maintenance and are a great compromise when removing the cowl.
