Description

The Spool Performance FX-350 Upgraded High Pressure Fuel Pump System is engineered for the AMG C63 M177 engine. This system features a larger bore size compared to the stock high-pressure fuel pump, resulting in significantly increased fuel flow capabilities. This upgrade is crucial for supporting higher horsepower and torque demands often associated with performance tuning. The FX-350 system is designed to provide consistent and reliable fuel delivery under demanding conditions. Availability is in stock, and the SKU for this product is SP-FX-M177-C63. The product also comes with an optional Ethanol Content Analyzer kit.
