You don't need it bud and by all intents and purposes, it's another useless part of the SR20DET in the GTiR.B1Ad3 said:Is this a spesific valve to the rnn14 or are all sr20 the same?
As I said above, bin it and all it's associated pipe work and the engine will look cleaner and be easier to work on plus, it might just sort your final niggles with the slightly hunting idle !
