PCZ Performance S55 Top Mount Charge Air Cooler Upgrade

BMW F80 M3 / F82 F83 M4 / F87 M2 Competition (S55 3.0L Twin-Turbo)

The factory S55 charge air cooler is notorious for heat soaking under load and failing internally over time, leaking coolant straight into your intake tract. The PCZ Performance S55 Top Mount Intercooler Upgrade replaces the fragile stock unit with a heavy-duty, high-efficiency bar-and-plate core engineered to drastically lower intake air temperatures (IATs) and hold heat at bay during back-to-back hard pulls.

Designed as a direct drop-in replacement, this unit features cast aluminium end tanks with integrated internal dividers to ensure even airflow distribution across the entire core. Whether you are running factory power or pushing Stage 2+ custom maps, this upgrade keeps your intake charge ice-cold and your engine safe from internal leaks.

Performance Benefits

• Drastic IAT Drop: Significantly reduces intake air temperatures to keep timing advanced and prevent power-robbing heat soak.
• Prevents Engine Damage: Eliminates the common OEM intercooler failure mode where internal core cracks leak coolant into the engine.
• Supports High-Boost Tuning: Engineered to support stock turbo setups all the way through upgraded full-frame turbos pushing 700+ HP.
• Consistent Power Delivery: Maintains peak performance during track sessions, drag runs, and hot summer highway pulls
