The E46 M3's engine is based on several race-developed engines - the S70/2 used in the McLaren F1 and the original S50 Euro engine released in 1995 and it traces its lineage all the way back to BMW's M1 inline-6. It blends racetrack technology with street car concessions. To keep your car running at its peak, you will want to invest in its care and that means a regular and strict maintenance schedule. The below M3 maintenance packages are standard recommendations from our experience and should be part of a larger overall service plan.

Keeping up with the maintenance on your car is the smart thing to do. For one thing, it prevents costly repairs in the future. For another, your car performs better, making aftermarket upgrades more worthwhile. And a well-maintained car with complete service records can add substantially to a car's resale value. Our service packages for your E46 M3 will ensure you get many more miles from your BMW street racer.

This package can be configured any number of ways to ensure you get what you need for a full Inspection I, Inspection II, or any other major preventative maintenance service. Our parts are OE, OEM, or performance alternatives that we have been using since 1993 so you get top quality parts, first-rate service , and unbeatable expertise .

Turner's Tip for a healthy S54:
+ First thing, stay on top of your maintenance. Nothing will hurt the performance and aftermarket upgrades more than a poor running car. And these cars like to throw codes that could be either small or a big problem. Find out fast!
+ Oil leaks are common from a small valve on the exhaust side of the engine block - the Constant Pressure Valve. At first glance it looks like a rear main seal is leaking but it's almost always this little gremlin.
+ If you notice a rattle coming from the front of the engine don't immediately assume it's the VAN0S system. The lower timing chain guide is held in with a bolt located behind the thermostat housing. This bolt has a bad habit of backing out which leaves the guide rail loose. If left un-checked for too long the guide rail will break and leave you with a very pricey engine rebuild. As a bonus you can replace the gasket on the oil filter housing as it's probably leaking too.
+ However, always make sure a VAN0S rebuild is in your budget too.
+ Have an engine oil analysis done annually. This will make it easier to spot internal engine wear, including rod bearing wear, as well as head gasket failure and coolant loss.
+ Check to see that your fan clutch is operating. The stock one has a high failure rate.
+ Power steering hoses - and their crimped connections - love to leak oil. It's almost always the high pressure line from the pump to the rack.
+ Rear subframe/floor failures - make sure you have this checked every year.
+ If you track it, make sure to change the oil often in the transmission and diff. This will be your first warning signs of a problem you can't see.

    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.

    Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

    Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

    From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

    As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

    Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

    To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

    See kit contents below for all included components.

This kit includes the ECS Kevlar Reinforced Drive Belts, tensioner assemblies, and new tensioner pulleys. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

    As the E46 M3 gets on in years and mileage, the cooling system will be one of the areas that needs the most attention. We have packaged all of the major cooling components into one overhaul kit:

    • radiator
    • water pump
    • thermostat
    • radiator hoses and clamps
    • gaskets and o-rings

    We have found that the E46 M3 can develop inconvenient cooling issues, even on daily driven street cars. While the infamous radiator and water pump failures of the E36 are a thing of the past, the E46 M3 still has its own complications. The best approach to avoid bigger problems is preventative maintenance. We recommend replacing the water pump before 80,000 miles and the radiator before 100,000 miles. By addressing these problem areas before a failure, you will save yourself a larger repair bill in the future.

    In addition to the standard cooling package items above, there are several other cooling-related components that may make sense to do at the same time:

    • Original BMW coolant
    • fan clutch
    • main serpentine belt and A/C belt
    • Turner Power Pulley Kit (because now is the perfect time!)

    This cooling overhaul package fits:
    2001-2006 E46 BMW M3
