The BMW M5 power and handling statistics are completely mind-blowing for a car tipping the scales at well over two tons. The S63 twin-turbo V8 is underrated from the factory and responds well to tuning and bolt on modifications. Calling it the ultimate super sedan would not do this car justice, it's just that good. But every amazing automobile must have an Achilles' heel, right? Some investigation into this model told us that enthusiasts were seeing elevated oil temperatures during track driving conditions. Our team set out to create a replacement, high-performance oil cooler that could handle the rigors of extreme driving conditions and the abuse of daily commuting. The Mishimoto S63 M5/M6 oil cooler features extremely precise CNC-machined billet-aluminum end tanks which are professionally TIG-welded to our robust bar-and-plate core. Our strategically designed 55mm-thick core provides a massive 24% increase in core volume, and a 40% increase in external fin surface area. This added surface area promotes greater heat transfer, which directly impacts internal fluid temperatures. Our performance oil cooler is a complete bolt-on solution that includes everything needed for an easy installation such as hardware and replacement O-rings for the oil lines. Our heat exchanger is finished in a durable silver powder coat, providing both corrosion resistance and improved aesthetics. Whether your M5 sees frequent track time or just the occasional back-road jaunt, upgrading the oil cooler is a great way to extend the life of your S63 and ensure maximum engine output when you need it most. As with all our BMW products, this oil cooler includes our signature Mishimoto Lifetime Warranty.

  • Robust bar-and-plate core resists damage from road debris and provides optimal cooling efficiency
  • CNC-machined billet-aluminum end tanks provide improved durability over stock stamped tanks
  • 24-percent increase in core volume over stock for improved cooling capacity

Good to know

Questions, answered straight.

If it is not here, call or text the counter. Real people, real answers.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
