Blow off valve
- BOV Type I -

The advantages over the series valve are obvious:
 
- clearly improved Responsiveness when accelerating
- significant faster Boost pressure build-up when changing gears
- EXCELLENT sound like many rally vehicles
- the turbocharger does not work against a pressure wall, this relieves the load on the bearing points of the charger and promotes them durability!
- Optimal exchange, if the original valve is too small or defective!
- The engine does NOT suck in heated air, which means you get more performance!

The Pop Off is made of aluminum and the surface is polished!

These are the pop off valves PISTON pop off valves and not about cheap membrane valves
The membrane often tears after a short time and the expensive valve is then thrown away because a new membrane is not available.

They are high-quality pistons that run in pop-off and are manufactured on the most modern CNC lathesearth.
The valve is cleanly crafted and has no burrs or edges, a safe one Sign of quality!

Even the cylinder in which the piston runs is made to fit so that no boost pressure reaches the piston too early
can escape because that would cost performance. You can go to high Precision and quality don't give up, because only
In doing so, you achieve what others are trying to achieve optimal performance increase!

For a boost pressure:
up to 1.00 bar - standard turbos.

 If you have higher loading pressures, you can order a different spring from us.
