4.2L FSI V8 Audi RS4 & RS5 upgrade High-pressure pumps BAR-TEK®

High-pressure fuel pumps for your V8 engine. We have converted the original fuel pumps to achieve a higher fuel pressure and a higher flow rate for your 4.2 FSI engine. Our upgrade high-pressure pumps deliver a full 50 % more than the standard pump ! The tappets are DLC-coated to minimise wear, friction and corrosion. A must for all tuned 4.2 FSI engines such as the RS4 and RS5. Also ideal for turbo and supercharger conversions. Because we have converted the original pumps, you can install our upgrade pumps plug & play. Depending on your choice, you will receive two conversion kits or two completely rebuilt, new pumps. Features of the BAR-TEK ® High-pressure pumps: Increases the petrol pressure thanks to a larger piston of 9.8 mm 50 % more power than standard pump Tested up to 8500 RPM A must for tuned FSI engines Less wear and friction thanks to DLC coating Important : After installation, the vehicle must NOT be started immediately ! Switch on the ignition and wait a little until the pre-feed pump has delivered the fuel supply to the high-pressure pump. Only then may the engine be started. Otherwise, the new pump may fail immediately! The software must be adapted after the conversion. Figure similar
