will a plenum spacer give me the most bang for my buck or is there a better mod that i could buy for $210?

 

Plenum spacer is one the best mods for our cars. Go for it.

 

I've been running my MotorDyne spacer for almost 3 years, it's the best mod
for performance I've made! motordyneengineering.com or 1-661-993-5111
Don't go anywhere else....

 

IMO search for a used one.. don't buy it new.

The plenum spacer is a GREAT mod for our car, i felt the power immediately after it was installed!

 

on there website motordyne is having a good deal on their spacer.

 

hey guys im gonna do a plenum spacer soon to. im not sure which one i should get though the basic or the iso thermal. it doesnt get that cold where i live. central cali, fresno to be exact. what do you guys think?

 

you guys convinced me a copper thermal is on the way. I would spend the extra $35 if you dont have the extra money wait to get it.

 

so which spacer is the best?

 

MD 5/16 Isothermal Spacer is all you need. I would buy directly from Motordyne.

 

I installed my MD 5/16 spacer yesterday and it is a great mod...way better than the Z-tube.

 

I installed a Stillen CAI yesterday and now I can really hear my car growl. You may look at upgrading to a Stillen next.

 

Sori if this is a noob question. I'm also debating which mod to do. What exactly is the difference between the Iso Thermal Plenum Spacer vs. the Iso Thermal MREV 2 Manifold? I notice that the MREV gives more hp..but Do u use both or you have to pick between the two Also what's the difference between the Copper Iso Thermal vs the Regular Iso Thermal? I just wanna know before I purchase from Jo...
