I have an 05 Evo VIII and im not sure which blow off valve to put in my car. I still have a stock turbo and im currently running an HKS SSQV with piping, and its recirculated. But ive been reading that the APS twin vent is one of the best blow off valves. Would it be a good decision to switch my HKS out for an APS?

 

This is all you need.

 

The better BOV for the EVO between those two is definately APS.

 

Naperville in the house. The APS is a great piece. If you don't plan to exceed 25PSI all you need is a IX DV.
