Benefits of installing the EGR bypass kit and removing the exhaust gas cooler
- Reduced contaminants in the intake—no backflow of exhaust gases means a cleaner intake manifold, less carbon buildup, and fewer deposits.
- More stable engine operation—less idle speed fluctuation, better throttle response.
- Improved performance and dynamics—the absence of hot exhaust gases in the intake improves fuel-air mixture quality and combustion efficiency.
- Lower risk of EGR system failures—elimination of potential failure sources (stuck valve, damaged actuator, controller errors).
- Less exhaust smoke—in many cases, combustion becomes more complete.
- Extended engine oil life – less soot entering the oil via blow-by.
- Possible reduction in fuel consumption—in some engines.
- Lower intake temperatures—which can have a beneficial effect on the turbocharger and intercooler.
Technical Specifications
- Plug material: acid-resistant steel, powder-coated
