What kind of plenum spacers are you guys using on your vq35de engines?
Width?
Brand?
Any problems(ie leaks)?
I,ve read that 1/2" is the thickest you can go and still retain the stock brace.
I'm thinking about getting the skunk2 5/8,
Thanks guys

 

cant' go wrong with MotorDyne 5/16" spacer. You really feel the bump in power. I didn't have any issues with it in the 3 or 4 years of owning it.

Becareful if you go get too thick of a spacer, you won't be able to install the front strut bar back on if you do. the hood won't have the clearance for it.

 

Yep you really can't go wrong with the 5/16" spacer, depending on what year is your Z you could even get the Mrev2 to go along with it for the extra power gain if your have a rev up engine.

 

I have the non rev up.
I,ve also heard the 5/8 will make you lose power is this true.
Thanks again for your input
