2006 Z - So I installed a Circuit Sports V2 mini oil catch can on the Z today & used some left over lines from Z1 that I had laying around. The kit came with a mini filter, a bolt if you choose not to use the mini filter, clear hose lines & 5 hose clamps. I didn't like the vacuum lines that came with the kit so I didn't use them. The kit has no mounting bracket so I just used zip ties. I'm looking to see if I can catch any oil using this system.

I also changed two vacuum lines in the back of the plenum 4mm lines slightly smaller than stock is this a bad idea? Would a 8mm line be better?

 

3/8 ID is the correct size
