With more than 50 years of experience and reviews across the world from magazines and race teams, Liqui Moly proves time and time again why they are one of the most innovative lead forces of performance automotive chemicals in the world. Turner Motorsport trusts Liqui Moly to keep all of our race cars - including the M6 - running smooth from the first hotlap to the last.

Turner Motorsport Recommends three Liqui Moly oil options for your BMW:

Leichtlauf High Tech full synthetic engine oil is designed to provide the highest amount of engine protection as well as fuel savings and reduced oil consumption - most BMWs like to drink oil, Leichtlauf should make yours less thirsty. Using proprietary blends of base oils and the latest additive technology, this oil will ensure smooth running gasoline and diesel engines in both high and low temperatures. Other amazing benefits include: optimum oil pressure at all speeds, rapid oil delivery at low oil temperatures, high shear and aging stability, turbo, multi-valve, and supercharger compatibility, and long service life.

Synthoil Premium engine oil is designed to provide great engine wear protection as well as fuel savings and reduced oil consumption. 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.

Our Turner Motorsport's full aluminum expansion tank was designed and engineered in house to help with the weak point in your E46 cooling system. The coolant expansion tank goes through heat cycles over and over again from regular driving, it is important that your expansion tank is doing its job to retain coolant to keep your engine operating temperatures down and keep your engine bay clean. Not only is this a major upgrade but also a great maintenance item to replace. Our expansion tank was designed to fit the OEM hoses for an easy install and comes with all the upgraded items you will need for a clean install.

If your BMW needs a new expansion tank, make sure this is the last expansion tank you ever need to buy. Our coolant expansion tank has a full aluminum construction and wrinkle black powder coat for durability. Expansion tank kit comes with all the accessories you need to replace your expansion tank once, and never have to worry about it again.

Our Performance CSL Air Filters start with a multi-layer synthetic dry cotton construction that contains millions of smaller fibers to provide superior filtration and performance over the OEM filter. Precisely manufactured for a secure fitment to ensure all the air entering your motor is properly filtered. With the CSL E46 only being offered in Europe, the OEM air filters are produced in much lower quantities making them harder to obtain and drive up the price. Turners solution is a price effective solution that offers premium filtration with increased flow, extended service interval and lifespan.

Having a clean air filter ensures your engine is running at its best efficiency! Proper air flow will help your engine breathe, get the best fuel economy and allow full power throughout the power band. Get the most out of your CSL intake with a new Synthetic High Flow Air Filter. These filters can be cleaned and reused for an extended service life.

Oiled versus Dry Filters:

Although both options will keep the air to your engine clean and improve airflow, there are a few differences to consider when choosing the best filter for you. Oiled filters allow better airflow than dry filters, however they require more maintenance. Oiled filters will likely get dirty faster, needing to be cleaned more regularly. When cleaning an oiled filter, it is necessary to oil them with filter oil afterwards.
Dry filters offer slightly lower airflow but are easier to maintain while still out performing the OE paper filter. Dry filters can be washed with warm soapy water. There is no oiling necessary afterwards.
Both dry and oiled filters flow better than stock and can be reused.
Product Features:

Direct Replacement for OEM filter
Increased air flow
Lower cost
Serviceable
Readily available
How to service an oiled air filter:

Take out your High Flow Filter
Gently tap your air filter on a smooth surface
Wash with warm soapy water a a soft bristled brush
Rinse with low pressure water
Let the filter air dry
Ready to reinstall for a fresh drive!

Replace the Achilles heel of your factory cooling system with a stout and reliable mechanical thermostat setup.

The factory E46 thermostat housing is a combined unit featuring a plastic housing and a built in thermostat that you cannot replace separately. These plastic all-in-one units are commonly know to crack or fail causing a headache, a trip on the tow truck and possible damage to your engine.

Taking cues from the reliable M50 thermostat setup we designed a an assembly that not only converts your plastic housing into a billet aluminum unit but also swaps out the integrated thermostat for a separate replaceable thermostat. The ability to swap out thermostats separately from the whole housing opens up doors to changing thermostats to different temperature ratings based on your application while also providing lower maintenance costs. No longer do you have to replace the whole housing but just the thermostat itself.

The billet housing is designed to be utilized with E46 M3 upper and lower radiator hoses and also features -16 ORB connections for custom radiator hoses. A major upgrade from the factory and aftermarket plastic units. Our thermostat housing kit can be used by the savvy daily driver or the track hero who wants to ensure the durability of their cooling system.

Key benefits:

Uses M50/S50 mechanical thermostat for increased reliability
Option to use aftermarket colder thermostats if desired
Thermostat can be replaced separately for lower maintenance cost
Barbed hose connections for use with E46 M3 hoses or built in -16 ORB connections for custom radiator hoses
Design:

Machined out of a single piece of billet 6061 aluminum, this thermostat housing will withstand higher prolonged temperatures and abuse for performance applications
Black anodized with engraved Turner logo on the front to match the Turner Motorsports Power Steering Reservoir
Viton gasket for superior sealing performance
For use with E46 M3 radiator hoses 11537830715 and 11537830716
Kit contents:

6061 Billet Aluminum Thermostat Housing
Mechanical Thermostat
Thermostat Housing Gasket
Thermostat Harness
Optional Silicone or Rubber E46 M3 coolant hoses
