The F90 M5 & F9X M8 are truly worthy successors to the F1X platform. BMW's S63 Twin-Turbo V8 is a tried and true power plant capable of big numbers. Like most turbo engines, cranking up the boost for those big gains creates a lot more heat. Fortunately for F9X owners, CSF is here to help keep those Intake Air Temperatures (IATs) down and your power up. CSF used CFD analysis and testing to create the largest charge-air-cooler that could fit in the factory location. The custom designed Liquid-to-Air Intercooler cores are 100% larger than the factory coolers. The single piece design integrates the charge pipe creating the strongest system possible.

  • Custom Designed CSF Liquid-To-Air Intercooler Core (CFD Analysis and Testing Completed to Ensure Optimal Performance)
  • Designed with 3D Scanning/Rapid Prototype Technology to Ensure Precise Fitment and Maximum Surface Area Utilization
  • Integrated E85/Methanol Injection Ports Built into Air Outlet End Tank (Dual 1/8 NPT Ports Per Cooler)
  • Significantly Reduces Intake Air Temperatures (IATs), Improves 60-130MPH Time By about 0.3 Seconds
  • 100% Increase in Core Volume Per Each Charge Cooler Compared to the OEM Charge Air Coolers
  • Sold As A Complete Set With Left/Right Charge-Air Coolers + Installation Hardware
  • Complete with OEM-Style "Quick Connect" Water Connections and Sensor Ports
  • 1-Piece Seamless Air Inlet End Tanks with Integrated Charge Pipes
  • "Drop-In Fit" Design with No Modifications Necessary
  • Lifetime Warranty

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.
