7 speed shop BMW performance Fuel Pressure Regulator 3.8bar 4.0bar

7 SPEED SHOP PERFORMANCE HIGH PRESSURE FUEL PRESSURE REGULATOR

3.8 BAR / 4.0 BAR

As engine output increases, so does the demand on the fuel system. 7 Speed Shop high-pressure fuel pressure regulators increase fuel pressure from the factory 3.5 bar to 3.8 bar or 4.0 bar, allowing your existing fuel injectors to deliver more fuel and increase overall fuel delivery.

This makes them ideal for engines with increased displacement, performance camshafts, or forced induction where additional fuel is required. For BMW M60, M62, M73, M50, M52, S50, and S52 engines. The 3.8bar regulator offers a slight bump in pressure which is great for milder upgrades, while the 4.0 bar should be reserved for Forced Induction applications

Not recommended for otherwise stock engines. Always use a wideband oxygen sensor to verify air/fuel ratio and confirm the need for additional fuel.
