I am using AEM CAI with my N18 cooper S (R58)
I am looking for Blow Off Valve Kit for the MINI Cooper S which can increase boost and obviously a loud Blow off sound for my car that can perfect fits with my AEM.

Any options or opinions?

 

FORGE Atmospheric BOV is amazing. I have it on mine. I scare the living **** out of people in NYC with it. lol

 

Before spending big bux do some research re: what the valve actually does and how it works. Next check out the Alta spring kit for about $15. You might be surprised.

yeah the spring helps a lot (I used one) but I think bank21379 is looking for some noise under the hood. The spring won't help that.

How'd you deal with the engine light? All I've heard about BOVs is that they cause a code to show up. I got a FORGE recirc valve and it's noisier than stock but not as noisy as a BOV plus no engine light.

 

I'd recommend the Forge Recirc Valve kit. It reacts faster and will hold more boost, but won't throw a light.
