hi can anyone tell me the best type of plugs to use on an imported my96 v limeted impreza thanks

 

Hi Kev,

If the car is modded use NGK PFR7B's if standard use 6's at 0.7mm

Cheers Red.

 

NGK PFR6's seem to be the choice for Standard to slightly modded cars but yours may be better with the colder NGK PFR7's due to it being an import with a slightly higher boost target.

Cheers

 

I have a 94WRX with a VOS CHIP fitted,(Ausy equivalent to the scoobyecu)

I have NGK PFR6's set to .08 and note sure if I should either lower the gap or change plugs to NGK PFR7's as the boost has increased to 16PSI

What the best option here..

thanks

Mark.
