CSF Charge Air Cooler for 2025 BMW G90 M5 and G99 M5 Touring: Direct-Fit Performance Upgrade

For owners of the 2025 BMW G90 M5 sedan or G99 M5 Touring wagon, the CSF #8351 High-Performance Charge-Air-Coolers stand out as the direct solution to manage the intense heat loads from the S68 4.4L twin-turbo V8 engine. This complete pair of coolers addresses the factory units' limitations in high-output applications, providing a straightforward path to sustained power and engine protection during aggressive driving or tuned setups. Built with precision for these specific models, the CSF #8351 ensures seamless integration while delivering measurable gains in charge air temperature management proven effective on vehicles pushing beyond 900 wheel horsepower on stock internals and scalable to 1000+ hp configurations based on real-world testing from prior S63-powered platforms.

Precise Vehicle Fitment

The CSF #8351 is tailored exclusively for:

  • Year: 2025 and newer
  • Make: BMW
  • Models: G90 M5 Sedan, G99 M5 Touring Wagon
  • Engine: S68 4.4L Twin-Turbocharged V8

This design shares compatibility insights from the F90/F92/F93/F97 X5M/X6M platforms, confirming bolt-on readiness for the G90/G99 chassis without major alterations to surrounding components.

Key Specifications and Construction

  • Part Number: CSF 8351
  • UPC: 710353083512
  • Core Volume: Nearly 100% larger than factory coolers per side, boosting overall heat dissipation capacity for lower intake air temperatures under load.
  • Design Process: Utilizes computational fluid dynamics (CFD) analysis and dyno-validated testing to maximize airflow through the core while minimizing pressure drop.
  • Finish: Standard OEM+ Crinkle Black for factory-like appearance and durability custom powder coat options available (e.g., Bengal Red Gloss or Fire Orange) with 3-4 week lead times.
  • Materials: All-aluminum construction with brazed plate-and-fin cores for corrosion resistance and thermal efficiency standard for CSF's high-output cooling systems.
  • Part Weight: Approximately 25 lbs (complete pair, based on similar CSF BMW applications exact figure varies by finish).
  • Shipping Box Dimensions: 48" x 18" x 12".

These specs position the CSF #8351 ahead of generic aftermarket options by focusing on model-specific engineering, ensuring it handles the S68's unique boost pressures and heat rejection demands better than unmodified stock units or less specialized alternatives.

What's Included in Your Purchase

Every CSF #8351 kit arrives as a complete, ready-to-install set:

  • (2) High-Performance Charge-Air-Coolers (left and right sides)
  • Factory-style mounting brackets and hardware for direct bolt-on fit
  • Installation guide (digital PDF available upon request)
  • Lifetime limited warranty against manufacturing defects.

No additional adapters or components are required beyond basic tools for the minor fitment tweaks noted below.

Installation Overview

This is a direct drop-in upgrade for the G90/G99 M5, typically completed in 2-4 hours by a professional installer. Key steps include:

  • Removing factory charge-air-coolers.
  • Shaving down OEM mounting pins for precise alignment.
  • Trimming the air balancing tube for clearance.
  • Securing the new units with provided hardware.

Results in fit and finish rely on installer experience detailed instructions and support are provided by CSF. Pairs seamlessly with CSF #8317 Engine Oil Cooler for comprehensive S68 thermal management in stroker or high-boost builds.

Why Choose CSF #8351 for Your 2025 BMW M5?

In a market flooded with universal coolers that compromise on fit or efficiency, the CSF #8351 delivers targeted performance tailored to the G90 M5 and G99 M5 Touring lowering charge air temps for sharper throttle response, reduced detonation risk, and consistent output across the rev range. It's the go-to for track days, dyno sessions, or daily-driven power upgrades, backed by CSF's decades of motorsport-proven cooling expertise. Secure your edge today and keep your S68 running cooler, longer.

Forced Induction

Forced Induction

Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...

Intercooler Components

Intercooler Components

Intercooler components let you build, upgrade, or repair your charge cooling system without replacing the entire intercooler assembly. Quality piping, silicone couplers, mounting brackets, and core upgrades make a meaningful difference in keeping intake temperatures low on high-boost builds and daily-driven turbocharged vehicles alike. Popular Upgrades Frequently ordered intercooler components include upgraded silicone coupler hose kits to replace cracked or blow-off-prone rubber hoses, intercooler core upgrades for higher bar-and-plate or tube-and-fin density, aluminum intercooler piping sets that replace restrictive OEM plastic pipes, and universal mounting brackets for custom intercooler positioning on fabricated builds. What causes intercooler components to fail? The most common intercooler component failure points are silicone or rubber couplers that crack or split under repeated heat cycling, plastic OEM piping that becomes brittle over time, and mounting brackets that fatigue...

Intercoolers

Intercoolers

An intercooler is the single most important component in a turbocharged induction system for supporting power gains from higher boost. By cooling compressed air before it enters the engine, an upgraded intercooler delivers denser, cooler charge air that allows more fuel to be safely injected and combusted, directly translating to more horsepower and torque. Popular Upgrades Best-selling intercooler upgrades include front-mount bar-and-plate aluminum intercoolers for Subaru WRX and STI, Mitsubishi Evo, and Volkswagen GTI platforms, direct-fit top-mount intercooler upgrades for rotary and compact turbo applications, and heavy-duty intercooler upgrades for Ford Powerstroke and Dodge Cummins diesel trucks where factory coolers are prone to failure under load. What is the difference between bar-and-plate and tube-and-fin intercoolers? Bar-and-plate intercoolers use a stacked aluminum plate construction that is more durable and provides superior cooling efficiency but adds more weight. Tu...
