After reading countless threads on CAI i've decided to get the Stillen CAI/Z-tube combo from EverythingG35.com. It goes for $239.99. The thing i cant decide on is between the 5/16" ISO Plenum Spacer or the Skunk 2 Plenum Spacer (5/8"). From reading the info on the skunk 2 it "outperform aftermarket manifold plenums currently being sold" Its also $100+ cheaper than the ISO.

What do you guys think?

 

i cant tell oyu about the MD, but im very happy with the skunk 2, big diference after 3500 rpms

Honestly, I've never seen a side-by-side comparison, or even an independent dyno for the skunk 2 spacer. I guess you just have to ask yourself if the $100 is worth having a product that you know will work well, vs a product that you're not sure (but might work just as well)

 

I am new to all these aftermarket upgrades. Where can I get these Plenum Spacers from?

 

i loved my skunk2 spacer...

 

remeber when you were younger and had to have the name brand ****..... As you got older and wiser; you still like the nice **** but would settle for something that looks identical but has a cheaper name... I think this is exactly the case with motordyne and skunk. You are paying 100 less and its basically doing the same justice.... I am ready to buy now and unless someone can tell me different. I spend a hundered bucks on a round of drinks at the bar so $ isn't an issue but if they are the same why pay more? Somebody enlighten me!!!!!!!

 

EverythingG35.com sells the plenum spacers and the skunk2
