Description

The COBB Tuning Fuel Pressure Regulator Manifold Reference Relocation Kit includes everything you need to relocate the FPR reference line to a more stable pressure source.


Why?

This allows for moving the fuel pressure regulator's manifold pressure reference away from the #4 cylinder runner and into a plenum-based source, similar to the method used on the previous generation 2004-2007 STI. This helps prevent unwanted manifold pulsations from affecting the FPR as the plenum is a common area of the manifold that represents the average vacuum/boost of all cylinders rather than a singular cylinder.

Rated 5 out of 5 by from No More Stumble I have had the fuel pressure regulator installed for a couple months and still had the stumble at ~3200 rpm. Now that I have the manifold reference relocation kit installed the stumble is gone. Made a great difference.

Rated 5 out of 5 by from Fantastic! No more stumble The install was simple, instructions were great, pics really helped. I wish I found this kit first rather than poring over endless forum posts about it.
