Prevents Costly Air Box Explosions!
Installed With The Air Box In Place
Porsche engines have had the habit of backfiring and blowing a hole in the air box.
This unfortunate event requires the replacement of expensive air box housings.
Our Pop Valve prevents this and is installed inside the air box.
When a backfire occurs the valve will instantly open and release the backfire pressure, saving your air box.
descrizione: Replace your restrictive air box and filter with a PowerFlow kit for improved air volume and velocity, and increased horsepower. A better breathing engine also gives you faster throttle response. Each design has been flow bench and engine dyno tested to assure maximum performance. PowerFlow kits include the PowerFlow intake unit, lifetime air filter, instructions, and all hardware.
