blow off valve
... The A4's system is closed loop. Meaning the MAF is dependent on the recirculated air from the Diverter Valve. If you got a Blow-Off Valve, you would run rich as Hell, and it would damage your engine, sensors, etc... It's not a good idea. I had an HKS Super Sequential on my Plymouth Laser for a while (Bought it like that, previous owner was a moron), and those systems are closed loop as well (Unless you get a GM-MAF-T set up for blow through). And the Laser would spit flames everything I would let off the gas, because it was loading up on fuel. Yes, this LOOKED cool, but it wasn't killing the car.
Just get a Forge 710N Diverter Valve and a Carbonio Air Box if you want to hear the Turbocharger and... The uhh... Ricer whip noise.
