just orderd a skunk2 plenum sapcer 5/8" . i went with skunk2 because for the price you get a larger diameter and its made out off "carbon composite material (carbon impregnated nylon-6) that offers superior thermal insulation characteristics which also increases power by keeping the upper plenum and charge air temperatures". let me know https://www.skunk2.com/Merchant2/ima...cts/plenum.jpg

 

What do you want us to let you know?

 

lol! yeah, whats do we let you know about? you mentioned you ordered it already. mayb'z let us know about it.

 

just wanted to see if anyone else hade it , but yeah ill let you guys now on it ill get it tomorow and instale it on saturday so ill let you guys know . peace

 

I'd be curious to see the real gains of the Skunk2 spacer.

I know they are a reputable company for the Honda/Acura tuning crowd, but are really new to the G35/350z world. The limited reviews I have read said to stay away from their product, in favor of the Motordyne spacers...

 

I would tend to agree^^

JM2C....
In a lot of ways.... a spacer is a spacer is a spacer;
except for, fitment & thermal isolation.

Don't know how well the SK2 fits so can't comment.
I do know that the MD is an excellent CNC machined piece.

For thermal isolation;
MD is def the product ...
with the thermal isolator on the intake manifold,
the entire plenum is isolated,
not just the top half

 

Turbo Magazine Has An Articale On These Spacer With Dyno Sheets

 

I had the Skunk2 spacers installed last week on my sedan. Fitment is fine.

 

I've had the Skunk2 for about 2 months. I didn't use silicone to seal it, but instead used a second Infiniti gasket on the upper section (cut out the middle section). No problems with fit or finish. No dyno though.

 

The dyno on Turbo magazine did an article and dyno the skunk2 plenum spacers. They made about 10hp. Not bad...

 

Based solely on a combination of what I have heard, read and experienced for myself . . . Motordyne is the only option for my hard earned bucks.
