Today I decided to replace my stock EFR integrated BOV with a billet replacement.

I must admit I never realised how crap the standard BOV really is until I replaced it. I don’t know why Borg Warner put so much engineering into this new series of turbocharger to completely cheap out on the BOV. No wonder there are reports of it exploding! (The BOV that is not turbo..)

What do you think? Personally I think the billet unit looks much better.
