Hi,

I am planning to tidy up my engine bay, change the intercooler rubber hose to hard pipe.

I have seen pictures of evo x with BOV before & after the intercooler. What is the different between these 2. I there any technical reason or only cosmetic. Which one is better? BOV before intercooler or after the intercooler?

thanks

 

after. ideal BOV placement is within 12" of the throttle body I believe.
