Air Box Pop-Off Valve Kit, For Porsche® 911®, 1973-1989

  • Prevents Costly Air Box Explosions
  • Includes Pop-Off Valve
  • Installed With The Engine And Air Box In Place
  • Epoxy For Installations & Installation Instructions

Porsche 911® engines since 1973 have had the bad habit of backfiring and blowing a hole in the air box. 911® Pop Valve is installed inside the air box and when a backfire occurs the valve will instantly open and release the backfire pressure. The Pop Valve then automatically closes and the engine continues to run. The 911® Pop Valve conforms to all emission regulations and has no effect on performance or gas mileage. CIS Injection Only
