Subaru Adjustable Fuel Pressure Regulator
Get your Subaru performing at its best
Want your Subaru running as smoothly as possible? Then make sure it's getting the exact right amount of fuel - for perfect combustion every time you drive.
With an adjustable fuel pressure regulator (FPR) you can adjust your Subaru's fuel pressure to ensure it's constantly fed with the optimum amount of gas for incredibly smooth - and superbly efficient - performance. Every time.
What is an adjustable FPR (and how does it work)?
Modern fuel injected vehicles run with fuel pumps in their tanks, and an internal regulator makes sure that a pre-specified amount of fuel pressure goes through the rails, with any leftovers sent back to the tank.
Yet, modified and upgraded air intake and exhaust systems don't take into account that more fuel is needed to make sure these parts perform at their absolute best. But with an adjustable FPR, you can tune the fuel pressure to ensure your engine gets the exact best mix of air and fuel, for perfect combustion and maximum efficiency in every drive.
