What sort of life should you get from spark plugs in the Trophy????? Just wondering, mines going in for it's 2nd svs in the next week, just hit 10k but not sure if they should be changed. never serviced a car without changing them b4.
The spark plugs don't need to be changed till the 72k service.
They are NGK PFR6E10 plugs which are excellent and dont need to be changed frequently. Ask any of the tuning companies and they will tell you that the standard leads and plugs are excellent.
