Yeah, I'm pretty sure Everything G35 is Infiniti of Scottsdale...

I've heard from a couple of the Z guys that put the Powerlab 3/8 on that it's pretty good... ( it's between the 5/16" & 1/2", so I'm not sure if you'd notice much difference from either of those to the 3/8", but I'm sure someone would know... )

Sounds good thanks for the help i'll check it out on monday and try to get it all figured out.. I might also wait till I go to California on the 30th and try to get one from joseph at Jspec. He has them for really cheap right now i'm just not sure where exactly he is located and if it is possible to pick one up on site

I would really like to know what you guys are talkin about haha.

I'm trying to get a plenum spacer on monday from a shop here in AZ and have it installed.

Whats it do though? Intake? New g owner here!

Congrats on the new ownership. It lets more air flow through the plenum giving a bit more Hp for a cheap price.

Thanks! here is my beauty! https://g35driver.com/forums/showthr...=223775&page=2

bit more hp meaning? like 1 or 2 hps?

Nice ride.

As for power, the Powerlabs states 6.9hp & 10ftq..

I'm not sure what the Motordyne puts out... ( would guess it's relatively close though.. )

Wow?? that much how come i havent heard about this??? how much do they run? I do want a CAI. Any suggestions?

Motordyne claims 13-16 to the wheels but who knows how true that is and thats for the 1/2" iso thermal. You can pick one up for around 300 after tax and everything

I'm going to go wash my car by myself right now haha and in this heat it may take me away but i'll be back later

I'm not 100% sure those #'s are accurate, as I don't have one.. But that's what Powerlabs claim. A couple of the Z guys I've talked to say it's a pretty good bang for the buck. As far as not hearing about them, I'm not sure why.. A lot of people talk about spacers ( maybe you've heard them called plenum spacers )..
As for cost... check HERE for some pricing... ( look for Plenum Spacer in the description )

You can also find these in the engine section of the marketplace as well ( mostly used, but that's not an issue on these )...

I have seen a number of back to back dynos on the motordyne spacer and it does make good power (~10+). Most of the aftermarket products gains numbers are false but the spacer is the best bang for the buck mod you can do!

Anywhere you recommend buying one and having it installed ON MONDAY i would like to drive and purchase one that day I could install it myself I just would like it monday
