Description

The Bosch CP3 Fuel Pump Upgrade Kit represents a significant enhancement for VW 2.0 TDI engines (CBEA and CJAA), directly addressing the known reliability issues of the stock CP4.1 fuel pumps. The CP4.1 is prone to premature failure, which can result in metal shavings contaminating the entire fuel injection system, leading to costly repairs. The CP3 pump, with its different internal design, has a long-standing reputation as one of Bosch's most reliable high-pressure fuel pump (HPFP) designs, offering increased peace of mind and dependable fuel delivery. Beyond its enhanced reliability, this CP3 kit also boosts efficiency and performance. It can deliver twice the amount of fuel compared to the stock CP4.1, making it suitable for performance builds aiming for up to 300hp. While compatible with stock turbochargers, it is recommended to pair it with upgraded turbochargers like the CR170 Bolt-On Hybrid, GTD1756vrk, or GTD2060vz for optimal results. The kit includes the CP3 R70 BOSCH Fuel Pump, an adapter bracket, various fittings, a sprocket hub, and all necessary hardware for installation. It is important to note that an ECU tune is required after installing the CP3 pump to prevent engine codes and ensure proper operation. The kit is compatible with Audi A3 2.0L CBEA, Beetle MK6 2.0L CJAA, Golf MK6 2.0L CJAA, Jetta MK5 2.0L CBEA, Jetta MK6 2.0L CJAA, Sportwagen MK5 2.0L CBEA, and Sportwagen MK6 2.0L CJAA models. All pumps are remanufactured in the EU, flow tested, and calibrated. The kit comes with a 12-month warranty.
