Blox Intake manifold plenum spacer

Spacers are spacers...they are all the same exact design...it really doesn't get much simpler than that. If you add other things then it might make a difference, but the spacer itself - they are all the same.

EDIT: Different brands with the same size (5/16(skunk, motordyne or 1/2in skun, motordyne spacer) are going to be the same.

Spacers....?
I've had my Motor Dyne ISO 1/2" spacer on for almost 4 years and did the
install myself. I don't believe it matters what the spacer is made of but what
is included with the kit, extra long bolts, plastic internal spacers and gaskets.
Not to mention the instructions Tony puts out with his spacers, a chimp with
an adjustable wrench could install his spacers....might need a torq wrench!

I would NEVER run a spacer made out of anything other metal because you need the best seal possible and sandwiching plastic between metal is never a good idea, especially when the metal and plastic have different characteristics under thermal load.

Although most plastics go liquid at about 500'F, there is a very wide range of usable operating temperatures among the different plastics.
Some plastics lose all their strength and turn mushy above 170'F. A plastic like this may still have a melting point of 500'F but that doesn't make it a good choice for this application. Strength/Temperature curves need to be known for proper evaluation.
In any case, all materials (and the respective material properties) used in MD products are well researched before put into application.

not all plastics melt though (such as all the products mentioned in my initial post)... The Skunk2 is plastic as well...
I'm not promoting plastic for a plenum spacer application (however there are more than one that do work)... I was just correcting the blanket statement that plastic cant be used - as it will melt... as a general statement that is incorrect.

Just an update on this. I had noticed that the car was a bit louder and more aggressive sounding but not really faster. Stock the car was running the 1/4 at 16.2 at 86mph. With the spacer/z-tube/k and n it was running 16.3-16.4 at 86mph most runs unless it got really cool and then would run 16.2 at 86.
I added the Greddy Evo2 exhaust and was still running 16.4s at 86. Took the blox spacer off at the track after running a 16.5 and ran a 16.2 at 88mph.
I suspect 5/8 is way to thick for the spacer and was causing issues.
