Air & Fuel Delivery

For your engine to perform at its peak, it needs a perfect mix of air and fuel. Grundig-Auto provides high-precision components for this critical system, ensuring optimal combustion, power, and efficiency.

EGR Delete

An EGR delete works by stopping your engine from recycling its own exhaust. By blocking the dirty EGR gas and tuning the ECU, your engine runs on clean air only. This eliminates carbon buildup, resulting in more power, better fuel economy, and improved reliability.

Ignition Coil

The ignition coil's function is to transform the vehicle's low battery voltage (12V) into a very high voltage (over 20,000V) needed to create an electric spark at the spark plug. This spark ignites the fuel-air mixture inside the engine's cylinder, starting the combustion process that powers the engine.

Blow Off Valves

A blow-off valve is connected to the intake manifold via a vacuum hose, located after the throttle body. When the throttle closes, the manifold pressure drops below atmospheric level, creating a pressure difference that activates the piston in the blow-off valve. This releases excess pressure generated by the turbocharger, either venting it to the atmosphere or recirculating it back into the intake system upstream of the compressor inlet. Blow-off valves are also referred to as diverter valves, recirc valves, or bypass valves.

Wastegate

A wastegate is the essential pressure-regulating valve on a turbocharged engine, tasked with preventing over-boosting by limiting turbocharger speed. Its operation hinges on a simple force balance: a spring presses against a diaphragm to keep a bypass valve closed. When boost pressure from the compressor outlet exceeds the spring's pre-set force, it moves the diaphragm, which opens the bypass valve. This valve redirects exhaust gases away from the turbine, bleeding off the energy driving the turbo and stabilizing boost pressure.
