CSF S55 F8X Cooling Package for BMW M3 and M4

Unlock consistent, repeatable power from your twin turbo S55 with this CSF high performance cooling bundle. Pairing the CSF top mount charge air cooler with the uprated front coolant radiator gives lower intake temps, faster recovery between pulls and excellent heat soak resistance on fast road, track days and drag use. A true plug and play upgrade that keeps OEM refinement while delivering race-bred thermal control.

Why this upgrade works

• Big drop in intake air temperatures for stable horsepower and torque, even after back-to-back runs
• Increased core volume and highly efficient water-to-air design for the S55’s charge air system
• Direct replacement fitment with OEM-style quick connects and factory shrouding retained
• Perfect for stock, Stage 1 and Stage 2 remaps that demand reliability and consistency
• Proven on customer cars; we’ve fitted and used this setup with excellent feedback and results
