Blow Off Valves

Hi there,

I own a 2010 335i, meaning it has the N54 twin turbos. I wanted to ask about blow off valves for the turbos. All I really know is that they make that *pfeww* sound, but other than that I know nothing about the cost, pros/cons, performance boost, or if people even do that to bimmers. Thanks for the help. I am new to the euro scene and totally digging it and trying to get the most out of the experience!

No need to do anything - stock they're silent. Maybe if you had a larger turbo, but otherwise, look to other mods. Forget dual cone intake for same reason.

Cal, strange that with all your experience with meth that you didn't suggest he step right up. Here's a vid of you back when you were whipping up a batch for your first few runs on the strip.

Mein Auto: e90 335i
OP, did you purchase your vehicle at a BMW dealership somewhere near Ontario? I remember seeing this 10 335i M-tech e90. It had a CF rear spoiler and plastidipped 335i emblems just like your pic in your sig. JW if that is the same vehicle. I think it had about 50k+ mileage on the car IIRC.
