I was wondering how often should I change the fluids and spark plugs on my evo? Not oil change but other stuff

 

People say the plugs are good for many miles, but they arent that expensive so i would change them every couple oil changes.

 

what? why?

 

The stock plugs are supposedly to be changed every 40-50k I believe on a stock car. On modified cars, it depends what's done to the car. I just changed my oe plugs on my mildly modified car at 25k because of misfire issues. Fluids, again depending on severety to the beating to the car, i'd do them atleast every 10-15k.

 

 

im running a mild setup and im on 54k miles and just about to change mine out and havent had any issues yet
