I just wanted to gather some information about how often evo owners change their plugs.

evo 8 or 9 owner?

How many miles do you let go by before swapping them out?

What plugs do you use?



Any information is great and helpful. I have an evo 9 with 7500 miles over 8 months. Is it time to swap them out?

TIA guys...

 

i hope not cuz i put bout 14k on mine since the last time they were changed lol i thought they didnt have to be changed till either 30 or 60k

 

every 5k but i'm using copper

 

Every 10 to 15k on the DSM. Haven't had the Evo long enough, but I'll probably do the same. They're cheap.

 

Every 10k on the IX using OEM Iridiums.

 

I have 37k on the clock and I last changed them for the first time at 14k....I checked them last weekend and they still look good.

I use stock plugs and I might change them only cause they have been in there for almost 23k miles...

 

I haven't changed mine yet. 27K. Might do it when I do the fluids.

 

Every 5-7K whenever they start fouling out, I go ahead and change em.

 

Every 15k Iridiums

 

every 10k on my IX

 

Every 12K, well at least my car told me to do it then or I would of went untill at least 30K. Carbon fouled

 

16k on my car, changed them about 5 times (lol. although that was because of issues with the car)

normal change should be about 5k miles using copper, theres no reason not to change them with how cheap they are!

 

33k, i think i should change them about now...hehe

 

I use NGK coppers so I change them every oil change, which is every 5k miles since I use amsoil. evo 8 btw

 

Just put coppers in last oil change so probably again soon...

Sekula (or anyone with the copper NGK's): what gap are you using?
