Upgrade your BMW G90 M5 or G99 M5 Touring with the latest CSF Charge Air Coolers, engineered to solve the weak points of the factory system. The stock BMW S68 charge air coolers struggle with heat and pressure under tuning, limiting the full potential of the car. CSF’s high performance charge air coolers deliver stronger construction, larger cores, and superior cooling efficiency — making them the go-to solution for enthusiasts pushing the limits of the new G9X M5 platform. The new BMW G90 and G99 M5 with the S68 twin-turbo V8 continues the M5’s legacy as the ultimate high-performance saloon. While the platform delivers incredible stock power, one of its main limitations comes from the fragile factory charge-air coolers. These OEM units struggle with heat and pressure when tuned, creating a bottleneck for power gains. CSF has solved this issue with the High Performance Charge Air Coolers, purpose-built for the G9X M5 and engineered to handle extreme boost, heat, and horsepower levels well beyond factory specifications. CSF has already proven the formula with its S63/S68 charge-air coolers (CSF #8178 & #8315) on the F90 M5/M8 and F9X X5M/X6M, trusted worldwide on 900+ whp builds. That same technology has now been refined for the G90/G99 M5, ensuring reliability and performance for both tuned street cars and record-setting builds. Key Features ~100% Larger Core Volume vs OEM factory charge-air coolers for maximum heat rejection. TIG-welded cast aluminium end tanks – replaces weak crimped-on OEM plastic tanks. Integrated cast aluminium charge pipe – eliminates glued-on plastic OEM charge pipes. CFD-optimised design for superior flow and reduced pressure drop. OEM-style quick connect water fittings and sensor ports for hassle-free installation. Dual 1/8″ NPT ports on both outlet air tanks for methanol/nitrous injection. Durable OEM+ crinkle black finish (custom finishes available at extra cost). Proven performance on world’s fastest S63/S68 builds including 1200+ hp applications. Lifetime CSF warranty against defects. Design & Engineering CSF’s engineering team leveraged experience from over 500+ S63 intercooler kits already in use globally. Using CFD (Computational Fluid Dynamics) analysis, CSF designed cores with maximum surface area and optimised fin density to control intake air temps under extreme load. The result is significantly improved thermal efficiency with minimal pressure drop, ensuring consistent performance under sustained hard driving, track use, or high-boost tuning. The one-piece cast end tanks and integrated charge pipe eliminate weak points found in OEM units, ensuring the system can withstand much higher boost pressures without leaks or failure. This stronger construction allows tuners and enthusiasts to safely push the S68 platform to its full potential. Real World Results Testing on a stock BMW G90 M5 produced 696 whp and 729 wtq on pump fuel. After fitting CSF High Performance Charge Air Coolers alongside an upgraded carbon intake system, performance exhaust, and tuning module, the same car delivered 757 whp and 828 wtq – gains of over +60 horsepower and nearly +100 lb-ft of torque. Importantly, these results were recorded in extreme 100°F heat and high humidity, proving the CSF coolers’ ability to maintain intake air temperature stability even under the harshest real-world conditions. Compatibility 2024+ BMW G90 M5 (S68) 2024+ BMW G99 M5 Touring (S68) *Fitment Notes: This product requires some minor modifications to install. The mounting pins that the coolers rest on will need to be shaved down to help the CSF coolers sit in a better position. CSF also recommends trimming the the air balancing tube to improve the fitment. The installation requires fine adjustments and aesthetic results will depend on the skill of the installer.

Returns Policy

1. Return Due To Change Of Mind

R44 Performance will happily accept returns due to change of mind as long as a request to return is received by us within 30 days of receipt of the item and is returned to us in original packaging, unused and in resellable condition. Return shipping will be paid at the customer's expense and will be required to arrange their own shipping. We unfortunately will NOT refund the value of any original shipping paid either.

Once returns are received and approved by our quality assurance team, refunds will be processed to the original payment method within 3-5 business for the United Kingdom and 5-10 business for other countries. We will notify you once this has been completed through email.

Please note that for any orders of Maxton branded products, there is a £15.00 restocking fee that they impose on all returns where it is clearly not their fault. Unfortunately due to the sheer volume of Maxton orders we receive, we are not able to absorb this cost and thus will subtract it from your final refund.

During sales, the sale discounts are only valid for new orders placed during the specified sale period and cannot be retrospectively applied to backorders.

Please be aware that gift cards are unfortunately non-refundable or exchangeable for cash.

For all parts sold where custom work was done, for example, IND custom-painted parts, these are sold at the customer's own risk. This means we cannot offer any refunds, returns, exchanges or credit if you no longer need or want the part. Due to the nature of custom work, we do not hold stock of them as we order them on a case-by-case basis. For any other queries please get in touch with our customer support team via email.

2. Warranty Returns

R44 Performance will happily honour any valid warranty claims, provided a claim is submitted within 30 days of receipt of items. Customers will be required to pre-pay the return shipping, however, we will reimburse you upon successful warranty claim. Upon return receipt of items for a warranty claim, you can expect R44 Performance to process your warranty claim within 7 days.

Once the warranty claim is confirmed, you will receive the choice of:

(a) Refund to your original payment method

(b) A refund in-store credit

(c) A replacement item sent to you (if stock is available)
