hey guys so im about to replace my intercooler pump and i want to do the dual pass endplate in the process.but my question is do i need the option b tank to?i have an 06 ss/sc with the zzp stage 2 kit and there s2 heat exchanger.

 

no. i've had the dual pass for probably 3 years now and am only now getting the parts for option b. while i don't know the details of the zzp stage 2, i'm running a 2.75" pulley, tuned, and i have a cx racing front mount heat exchanger with the dual pass as my only cooling mods and i'm fine.

 

You dont NEED it but it helps with getting air out of the system.

 

ok cool that frees up money for extra goodies lol.and im running the 3.0 pulley with a custom tune.
