I like my forge bov. I ahve a stock replacement if you need it.

 

Some sound clips and videos of various BOVs here:

Yes that's a much better angle, that first pic really threw me off. I'm obviously not familiar with the HKS at all.

 

i will have to try removing the insert and try it and see if i like the sound better. U have a different flange then me so it is harder for me to install mine under the hood so i am getting some new IC pipes made.

 

Sorry I couldnt chime in earlier...

I have the 50mm Tial. Its a bad boy BOV. You can get different spring rates, the stock is 13psi which is about right. It does need a decent vac signal to actuate though, the stock lines and LR silicon didnt really do the job. You may want to drill out the banjo or create a dedicated line. Obviously you will need a new IC pipe to weld the V band fitting to...
