VIS Motorsport High Pressure Fuel Pump Internal Upgrade Kit – Audi C7 RS6/RS7 4.0 Twin Turbo EA824 V8

Unlock the true power of your vehicle with our high-performance fuel pump internal upgrade kit. Designed specifically for the Audi 4.0L TFSI (EA824) engine, this kit is a must-have for anyone looking to push their car to the next level. Whether you’re building a “big turbo” monster or simply want to optimize your stock setup, our upgraded pump internals deliver the extra fuel flow you need.

Key Features & Benefits

• Boost Fuel Pressure: Our internals are engineered with 20% more surface area, allowing for up to 10 bar of additional fuel rail pressure. This directly translates to more horsepower, even on a stock setup without a software upgrade.
• Built for Power: Capable of handling over 150 bar of pressure, this kit is ready for high-demand applications and big turbo builds.
• Precision Engineering: Each piston head is optimized for ideal fuel flow direction and undergoes a two-stage hardening and heat treatment process for maximum durability.
• Enhanced Traceability: A unique laser marking on each component provides better traceability and protects against counterfeit products.
• Complete Kit: This kit includes all the parts you need—one set of internals for each of the two high-pressure fuel pumps on your engine, along with a specialized installation tool to make the job easier.
