The AutoTech 10-127-101K (often referred to with the "CK" suffix for specific kit configurations) is the premier high-volume fuel pump internal upgrade for modern Audi and Volkswagen FSI/TFSI engines. Engineered to eliminate fuel starvation in high-horsepower applications, this kit is the industry benchmark for tuners pushing Stage 2+ levels and beyond.

High-Performance Fueling

This kit replaces the factory high-pressure fuel pump (HPFP) internals with a larger 11.5mm piston. By increasing the effective displacement of the pump, it provides a massive 50% increase in fuel flow over the stock configuration. This allows your engine to maintain stable fuel rail pressure even under the extreme demands of upgraded turbochargers and aggressive tuning.

Precision Engineering & Durability

  • Plasma DLC Coating: Autotech was a pioneer in using Diamond-Like Carbon (DLC) coatings on fuel pump components. This specialized plasma coating reduces friction and heat, significantly extending the life of both the piston and the cam follower.

  • Match-Ground Tolerances: Each piston and cylinder are match-ground multiple times during manufacturing to ensure perfect tolerances. Every kit is serialized to guarantee it meets Autotech's strict quality standards.

  • Increased Performance: Users typically see a notable increase in low-end torque (approx. 5%) and an additional 10 Bar of fuel rail pressure capability, providing a "cushion" for high-load scenarios.
