1.6T T9511 1.6T Deceptor Pro II In Cabin Adjustable

Blow off valve works great but the control switch worked for only a day.

The best out there

I've had this on my car for two years now with no issues. Setup was a breeze, the hardest part was fishing the wires through the firewall. I love being able to adjust venting to atmosphere or recirculating on the fly. Great for those rainy days and winter months. It's got plenty of volume at max settings, sounds like a big sneeze with no whistle. Might buy the bigger horn eventually to get that whistle though.
