Mishimoto BMW E46 M3 Oil Cooler Kit (2001-2006)

Key Features

  • Direct fit for the BMW E46 M3
  • Reduces oil temperatures by 30 F (16.7 C)
  • 10 psi reduction in pressure loss
The S54 is an incredible feat of engineering. Smooth power delivery, individual throttle bodies, and an 8,000 rpm redline make for an unforgettable driving experience. As with any BMW, maintaining optimal oil temperatures is key to extending the life of your vehicle and ensuring that you're getting an unparalleled driving experience. As many of these vehicles see frequent track time, the team at Mishimoto decided to develop a performance oil cooler kit that would provide improved durability and deliver the power needed for track driving. The result: an extremely efficient core with a proven 30°F (16.7°C) drop in oil temperature. With an increase in core thickness of 110%, this oil cooler kit raises your oil capacity by 0.44 qt. The oil cooler end tanks, cast from a single piece of aluminium and TIG-welded to the core, have been designed for maximum reliability, giving you the confidence you need to push your E46 M3 to the limits.

This oil cooler kit is designed as a complete bolt-in fit, requiring no modification to work with the stock radiator or the Mishimoto BMW E46 Performance Aluminium Radiator. To ensure a complete direct-fit, Mishimoto engineers have designed a fully CNC-machined 6061 aluminium and 303 stainless steel BMW E46 Oil Line Fitting Kit, which makes the removal of the stock hard lines and installation of stainless steel braided lines a simple task.

This kit includes pre-assembled stainless steel lines with -10AN fittings to help direct the oil to and from the cooler, as well as a black Mishimoto Oil Line Stay to keep your lines from rubbing. As with all our products, the Mishimoto E46 M3 Oil Cooler Kit includes the Mishimoto Lifetime Warranty.

Please note: Mishimoto fully inspects and cleans all products prior to packaging. However, it is recommended that customers flush the oil cooler with one quart of clean oil prior to installation to remove any debris accumulated during shipping. Please feel free to contact us at support@mishimoto.com if you have any questions.

Who you are buying from

You are buying from a drift team, not a warehouse.

Our founder competes himself in his own drift E46. Our team build and race the same platforms you drive and work on, and our sponsored drivers chase championships on the same parts we sell worldwide.

01

We have already broken it for you.

Our founder, a full team of sponsored drivers, and hundreds of other drivers worldwide are out competing on this stuff in drift and rally. When we tell you a part is good, the part is good. It has already been put to the test.

“After trying a few better known brands such as Tilton and Extreme, and never being super happy... Conor was able to recommend me the perfect clutch for my application... I havn't broken any drivetrain parts since I installed it.”

Connell O'Kane, 2JZ drift car, 27 Jul 2024

Tell us the car. We will spec it.

Chassis codes, spring rates, angle kit clearances, clutch ratings. Send us the car and what you want it to do. The answer comes from someone who has run that setup, not someone reading a product sheet.

Ordered before 1pm, fitted this weekend.

In-stock parts ordered before 1pm are dispatched the same day. UK and Ireland typically arrive next morning, worldwide as quick as three days. Times do vary, but that can mean the part is on the car within a few days and she is back out blasting the roads by the weekend.

Straight answers

The questions you were about to open a chat about.

How do I know it will fit my car?

Send us your chassis code or your reg in the chat and we will confirm before you spend anything. If you order and it turns out to be the wrong part, we swap it.

“Had a mix up with the item description (order wrong part) they was quick to email me and see what part I was meant to order and substituted it for no extra cost!”
Bradley Page, verified customer, 31 Jan 2025

When will it actually arrive?

In stock and ordered before 1pm, it leaves the same day. UK and Ireland is usually next day, occasionally 1 to 3 days. Europe 1 to 5 days, rest of world 3 to 5 days on express.

If something is not in stock, we will email you right away with an ETA and any available substitutes. On the rare occasion it does not work out, we will happily refund your order.

Will I get stung for customs or import VAT?

No. The price you pay on our website is what it will cost to be delivered to your door. You will not receive any surprise surcharges after ordering.

What if I change my mind?

30 days on all stock items, full refund on the parts. If you ordered the wrong thing we will help you get to the right one for as little money as possible. We have been there.

What warranty do I get?

Everything on our website is covered by the standard manufacturer's warranty.

If you ever need to claim, we fight your corner. We will do everything in our power to make sure you are looked after, rather than leaving you to argue with a manufacturer on your own.

Can I pay it off over a few months?

Yes. Klarna and Shop Pay Finance are both at checkout, so you can spread it without putting the build on hold.

Can I just ask someone what to buy?

That is the bit we are actually good at. We run our own race team and workshop, so you are talking to someone who has fitted it, broken it, and fitted it again. Hit the chat and tell us what the car is doing and what you want it to do.
