Air Box Relief Valve for Porsche 911 (1973-83)

Air Box Relief Valve for Porsche 911 (1973-83)

Air Box Relief Valve for Porsche 911 (1973-83)

Don't blow a hole in your airbox! Older air cooled motors love to backfire on cold start. With a sticking cold start valve, the backfire pressure can just destroy the whole airbox. This valve instead will give your motor a safe way to get rid of the excess pressure, it opens, then snaps back closed, re-sealing the box.Ā 

  • Guaranteed Fitment
  • 24 Month Unlimited Mileage Warranty
  • High Quality Materials
  • Replaces leaking OE air box pop-off valve that can reduce vacuum and degrade engine performance
  • Manufactured to original valve specifications for easy installation and reliable performance
  • Durable high-quality materials withstand high temperatures and rapid vacuum fluctuations
