Benefits of installing an EGR plug

  • 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 responsiveness—the absence of hot exhaust gases in the intake improves air-fuel mixture quality and combustion efficiency.
  • Lower risk of EGR malfunctions—elimination of the source of failure (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;
  • all plugs undergo specialized vibratory finishing. This process removes sharp edges and smooths the surface
  • Gasket material: GAMBIT AF-1000—a material with exceptionally high strength properties, resistant to all conditions in the exhaust system
  • Note: Plugging the valve may cause a warning light to illuminate on the dashboard. In this case, the EGR valve must be deactivated via the vehicle’s software.

Aditech Sp. z o.o. assumes no liability for the use of this part on public roads where the removal of emission control devices is prohibited.
