Autotech High Pressure Fuel Pump (HPFP) - Audi/Porsche EA839

DESCRIPTION Autotech is the premier manufacturer of fuel pump upgrades for direct injection engines because our kit offers the highest quality, solid engineering, and great value. Each piston (11.81mm) and cylinder in AutoTech High-Pressure Fuel Pump kit undergo high-precision grinding processes many times during their manufacture, ensuring that the most precise tolerances are maintained through the final step. Not the cheapest way to make them, but the best way. Each piston and cylinder are match-ground and serialized to ensure absolute precision and the utmost longevity. Autotech was the first to incorporate plasma DLC coating on HPFP components to reduce friction losses and increase performance. Others have tried to follow by adding a coating to their parts. However, the DLC process alone is not enough it is not a cure for substandard precision the parts must be engineered specifically for the process to take full advantage: Autotechs are. The success we have in the field can attest
