COBB Tuning Fuel Pressure Regulator Manifold Relocation Kit - 2008-2021 Subaru STI

Spectral Performance proudly carries a great selection of quality performance upgrades brought to you by COBB Tuning.

This is the COBB Tuning Fuel Pressure Regulator Manifold Reference Relocation Kit. This kit includes all the components to successfully relocate the fuel pressure regulator reference line to a more stable pressure source. This allows the user to move the fuel pressure regulator's manifold pressure reference away from cylinder #4 cylinder runner, and into a plenum-based source. This prevents unwanted manifold pulsations from affecting the FPR because it now utilizes pressure from all cylinders rather than just one. 

DETAILS:

• Improved vacuum reference for the FPR - Plenum based (COBB) vs the OEM individual cylinder runner
• Reduced "T" fitting
• 4mm and 6mm silicone vacuum line
• Includes black zip ties
