I tried the search function and found nothing. Does anyone know why ZEX is supposedly bad for Maxima's? I heard someone say that NOS is better than ZEX. Please help

 

You can go either or but NOS is easier to install. ZEX isnt bad or anything. I think the ZEX comes with a little controller pack that adjusts the timing on cars but with the 4th gens, the timing cannot be adjusted.

I know that some of the NX kits work according to bottle pressure and how much NOS to deliver.
