Fuel Pressure Regulators

One of the most important parts of a high performance engine is its fuel system. After years of testing on the dyno use, and real-world track testing we have dialed in which brand will give you the most reliable and performance advantages.

We carry a huge selection of the highest quality fuel injectors, fuel pumps, fuel, rails, regulators, sensors and more. We build and race some of the fastest Subarus in the world, and these are the parts that get us to the top!
