Zex Nitrous Solinoids

I have the zex perimiter plate but used the triple threat solenoid set-up and it is sweet all 3 solenoids on a aluminum block and having purge is sweeeeet--Nice piece for the money not to mention the triple threat is rebuild-able and the wiring is a molar connector Also they are a quarter of the size of the solenoids that came with the plate system--Steve
