Hey Guys-

as the title says, i just ordered my R2C MaxxFlow intake for my Stock 06 sedan. In all of my readings, i am seeing that the R2C combined with a plenum spacer should give me a nice little boost in power.

but When looking into the MD spacers, there are a few options, first theres 5/16", 3/8" & 1/2"

on top of that there is the Basic, Isothermal & Copper

from what I've read, the 5/16" seems to be giving the biggest increase in power, (please let me know if im wrong) But when it comes to the basic Vs. isothermal Vs.copper, Im lost.

I read some people saying that the isothermal and copper are for colder weather regions, is that true? if so, Im in SoCal, should the Basic be sufficient?

any help/insight is appreciated.

thanks

 

5/16" basic is fine for you.

if you have revup engine go for the mrev2 either over the spacer or in combo with. If you have revup the spacer is worthless alone.

 

Great! thanks for the info!

 

+1 on the basic 5/16", try and find a used one if you can, they all work the same
