Mercedes M276 C43 Intercooler kit

Spool Performance is excited to bring you our high-performance air-to-liquid intercooler, designed specifically for Mercedes-AMG models with the 3.0L V6 bi-turbo engine (M 276 DE 30 AL), like the C43, GLC43, E400, and E43. We started by 3D scanning the stock intercooler, then completely reworked it to maximize every millimeter for better performance.

Why Choose the Spool Performance Intercooler?

• Huge Cooling Upgrade: Our intercooler features a 140% larger core than the factory unit, 5% larger end tanks than competitors, and a tighter fin density to keep charge air temps consistently low.
• Precision Engineering: Milled from a solid aluminum block using CNC machines, this intercooler is built to last and handle the demands of high-performance driving.
• Better Airflow, More Power: With smaller row widths (5mm vs. 6.8mm) and closer fin spacing (2.5mm vs. 3.5mm), it flows air more efficiently than the competition, delivering cooler air to your engine.
• Upgraded Charge Pipe: The included charge pipe increases diameter from 42mm to 53mm, reducing restrictions and improving performance.
• Built Tough: Oversized welds and durable construction make it reliable for both daily driving and racing, all while minimizing backpressure.

• CNC-Machined Mounting Brackets for a perfect fit.
