When upgrading WRX grey injectors to 440`s
 

When upgrading the grey WRX injectors to the yellow 440`s, do the grey injector caps fit the yellow 440`s so its a striaght swap, phase 1 models ?

cheers

if you are fitting phase 1 440,s to replace the grays then yes they do i believe (someone will correct if wrong). if its phase 2 440,s you need the carl davey spacer kit.

Cheers for the reply, yes, im fitting phase 1 440`s to a phase 1 wrx etc

cheers again
