VTT Billet B58/S58 HPFP Block-Off Plates

When a B58 or S58 build goes to port injection only, the direct-injection system and its high-pressure fuel pumps come off the engine. That leaves open pump ports in the valve cover, and they have to be sealed properly. These billet aluminum plates close them off.

What you get

• Billet aluminum plates that seal the HPFP openings in the valve cover.
• Straightforward swap. Pull the high-pressure pump and its cam follower, then fit the plate where they sat.
• A clean result. The pump is gone from the engine entirely instead of sitting there disconnected.

Good to know

• Removing the HPFP usually means the car will need a standalone ECU.
• Only for engines that have dropped direct injection completely.
