Autotech High Volume Fuel Pump Kit Audi B9 S4 EA839

Description

High volume HPFP internals for the EA839 3.0T V6 in the B9 S4 and related Audi applications. Part of Autotech’s HPFP range, made in California with a lifetime warranty.

Key Features:

• Match-ground and serialised: Each piston and cylinder is precision-ground repeatedly through manufacture and paired as a set, not assembled from batch parts.
• Plasma DLC coating: Autotech were first to apply diamond-like carbon to HPFP internals to cut friction. The coating works because the parts are engineered around the process rather than coated afterwards.
• Removes the pump as a limit: Flow headroom of up to 50% over the factory pump, so fuel delivery stops being the constraint even on large turbo upgrades.
• Tuner-supported: HPFP-specific calibrations are widely available, so the hardware has software behind it.
• Lifetime warranty: Autotech warrant their parts to the original purchaser for the life of the vehicle they are fitted to.

Fitment:

• Audi B9 S4 3.0T EA839
• Audi B9 S5 3.0T EA839
• Other EA839 3.0T V6 applications

The B9 S4 EA839 three-prong fuel pump tool is required for installation and is sold separately.
