The Exhaust Gas Recirculation (EGR) valve is an important part of your car’s emissions system.It recirculates exhaust from the engine’s combustion chamber to burn again rather than sending it to the emission system, thereby reducing emissions. The EGR valve opens and closes during the engine...
When the injector is energized, an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle. The nozzle is designed to atomize the fuel — to make as fine a mist as possible so that it can burn easily. The amount of fuel suppl...
which needs to be removed. Below that on the TIP (sticking out above and to the left of the PCV valve in the picture) is the N75 valve, which is part of boost regulation. Both of these need to come out, and they're b...
