they dont list the 350z in their application guide but do list VQ35DE.

if this fit our cars do you think it's a legit or a sh*t product.

 

It seems kinda pricey, you can get the isothermal kit from Motordyne for $50.00.

 

It's legit, but it is for the 02-03 Maxima IM.

 

Im assuming it makes most of the power not from the isothermal part but from the spacer part.

 

Carb spacers were one of the most cost effective ways of gaining some more HP.

I'd like to see what Tony thinks of this

 

thats amusing, i would like to meet someone ballzy enough to take their headers off to stick those spacers on there.... waste of money, get the ISO thermal upgrade with your spacer selection, and blow that out of the water.

 

Wait til my Megan's crack and I might

 

FWD VQ35de's are not the same as RWD VQ35de's. So you cant compare this product with the spacers on our z's.
