hi all, i did a search so i hope this isn't a repost.

i was wondering if the nipple on the Greddy type s bov needs to be caped off. this is not the one connected to the vaccume line, it is the one below it slanting out.
thanks

 

From what ive read, alot of people cap it off, some people dont, its up to you. If it runs fine not capped leave it be.

 

heres a pic, it's the lower one on the left.

 

do not cap........if you are running recirculated and still want a nice type s noise

 

thanks guys, just wanted to make sure everything was going to work properly.

 

cap / uncap = didnt change the noise on my evo

 

Just got my Greddy BOV in and installed on thursday and its awesome. Just follow the instructions that evomoto.com has posted on their website for the installation and you'll be good. It's a great valve!

 

i had mine both ways dont seem to make a difference i have it uncapped now

 

Just installed mine 2 days ago and its not capped off and It performs and sounds amazing. The softer you go the louder the BOV is.
