Cobalt & Ion ---> ZZ Performance


It is the Boost Reference fuel pressure system..

I read everything on the ZZP page and still didn't fulllly understand what it actually does, and how it benefits.

If someone could explain it to me, that'd be grand.
Thanks.

 

basically it puts a normal fpr in your car rather than the computer controlled pwm pump unit. For what the kit does its not exactly the best deal. You could do it yourself for quite a bit less.
