Hey guys I'm looking to get a little more power out of my G... So far my only hp mod is the ztube intake kit... I also got stillen sways and tein lowering springs. What other mods can I do to gain some hp? Is there a performance chip I can get? I know I wanna upgrade exhaust too, probably hks... thanks guys

 

search

no chip

motordyne spacer is good for 12-14 whp and it's only 220 bucks

 

actually the spacer is on sale at everythingg35.com for 198

 

Go with Mrev2 cheap mod for around 15 hp

 

no need for a mrev2 on a 04...+1 on the motordyne 5/16 iso spacer

 

how difficult is the install for the spacer?
What is the mrev2?

 

I had NO experience modding before I got my 1/2" spacer (install is the same) and I was able to do it w/ a socket wrench and a youtube DIY.. Didn't even look at the instructions that came w/ the spacer.. VERY simple install..

 

ok thanks... What does the spacer actually do to create more hp?

 

allows more space for the air to tumble around in the plenum before going into the gasket..

 

The spacer does what it's named for: creates a space in between the upper plenum cover and the intake gasket. The original design of the plenum and gasket did not leave enough space in between the front two cylinders, effectively starving them of air. The spacer allows more air to enter and practically restores the full use of the two cylinders = giving you more power than stock.

Mrev2 is for 05 rev up motors i shoulda clarified that ....u got 04....sowwy

 

Ok thanks guys I think I'm gonna go with the 5/16 spacer, but what's the diff between ISO thermal and just the regular plenum spacer. Is it necessary for me to get the copper iso thermal plenum since it does snow where I live maybe 3 times a year... I never drive the G in the snow, but do in the cold weather...
