BMW Maintenance & Tune-Up Parts for BMW 3 Series E46 (1999-2005)

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.

How to service an oiled air filter:

Rinse with low pressure water

Pentosin CHF 11S hydraulic oil is a specially designed synthetic oil crafted for various vehicle hydraulic systems. It serves power steering, level control, hydraulic suspension, and shock absorbers. With a broad temperature tolerance, it suits both hot and cold climates exceptionally well. Meeting DIN 51 524T3 and ISO 7308 specification standards, this oil ensures quality and performance.

Regular maintenance, including fluid drain, flush, and refill of the steering fluid, removes contaminants and revitalizes fluid additives. This process safeguards against abrasion, chemical attacks, and corrosion, ensuring system longevity and efficiency.

This is the sensor / sending unit that notifies the computer if your coolant level is low. When this fails, it can give a false indication of low coolant -- or worse, not inform you of a low coolant situation which could potential cause overheating. (Note: This sensor is also found in the windshield washer container, to alert the computer when you are low on washer fluid)

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This sensor also serves as the washer fluid level sensor on many models.
