i was wondering what would be a good plenum spacer to get for my coupe? any good brands in mind? im willing to spend at least 300... let me know what you guys got. thanks

 

Motordyne 5/16" Iso Copper

 

MotorDyne

as for the size 5/16 or 1/2 do some research on that. 5/16 gives you power all throughout the RPM range while 1/2 gives you more power at higher RPM's

 

I have this installed...awesome for Vancouver (colder) weather

 

Dude go with the mototdyne 1/2 iso thermal. I did the install last week and i get power through all the bands and it growls now lol. Remember bigger is better thats why it cost more.

 

okay btw, would that give enough way for a front strut bar?

 

do you have a g35 coupe? Do you have aftermarket strut bars on the engine? if you answer yes to the second question, then i dunno know if it will fit. I also did the 350z hr y pipe.

 

Well I guess I'll chime in with another MotorDyne spacer vote. If you get a upper strut bar that's adjustable like Richie's you won't have an issue with clearance. Some bars won't fit because they're not adjustable. I have the MotorDyne 1/2" spacer ISO with Richie's bar and it fits on my coupe....

gary how do you like the 1/2 spacer, doesnt your car growl lol

 

i have the motordyne 5/16 copper spacer.
i love it! i have more ummpppphhh at lower
RPM's and the sound is killer with my Fujita Intake

 

i got more ummph with the 1/2 as well

 

Hell yes Slick growls, that's why we never leave the garage without having a good time. When I consider all the mods I've made
including 4 aftermarket exhaust system (two sponsored) the MotorDyne 1/2" spacer is the only one I consider the best value for
dollars spent performance wise. They all work together from Stillen's intake thru the MD spacer to the HKS exhaust for added HP
and the sound I love....

opinions on the powerlab 3/8 billet spacer?

 

how much difference are you looking at when you're talkin 5/16 vs 1/2

I've been eyeing the MD 5/16 ISO for a little while noww.... I'm also wondering what money is involved with adding aftermarket struts and how that'd affect using the stock engine cover...
