PFS S58 Port Injection Block Off kit

PFS S58 Port-Injection Block-Off Kit

The PFS S58 Block-Off Kit seals the injector ports left in a drilled factory intake manifold when a port-injection system is removed. It allows the existing PFS rail to retain the blanks or can be ordered with a replacement rail so the original PI assembly remains complete.

Kit Contents

• Six injector-port blanks
• Optional replacement fuel rail, when selected

Installation Overview

1. Remove the port-injection wiring, hoses, injectors, and related hardware.
2. Install the six blanks into the prepared manifold ports.
3. Install the existing or optional replacement rail.
4. Secure the rail with the three factory screws.
5. Confirm every port is sealed before operation.

Fitment

Designed for S58 factory intake manifolds previously drilled for the compatible PFS port-injection kit.

Safety Note

Depressurize the fuel system before service. After installation, perform a complete vacuum, boost, and fuel leak inspection. Professional installation is recommended.
