Hi everyone I recently purchased an evo ix when I bought it it had 48k miles now it has 51k I decided to change the spark plug... I wanted to know if its normal for the old spark plug to look like the ones on the pictures or does my evo ix might have a problem?

 

What Picture ? Also my tuner recommended changing plugs on a turbo car every 20k i believe i think he said 10k but to me that low. So if the plugs look like crap they might be original plugs

 

Yeah it looked like crap I was scare

 

Thanks for replying

 

they look original so 50k i would change them also depending on your tune your car could be running rich i would replace them. Have you been having any issues or did you just wanna replace them and want information on the look of them

 

Well I went to a friend house I we decided to checked them but the car did not had any issues it was running good...the guy that I bought it from said that he took it to hb racing to get it tune and he also gave me the dyno sheet the car has an HKs intake , greddy oil catch can,invidia catback and a torque damper

 

They don't look too bad, pretty normal. Did you check the gap of them? If I was in your situation and just bought the car I would replace them too. Reason for that is because every time I buy a car I always do all the maintenance.

 

 

Every car that I buy before I start driving it I do all the maintenance, and do a complete detailing of the entire car.

The plugs look old to me and I would change them even if they only had 5k miles on them.

 

I didn't checked the gap .....I replaced them with the same ngk spark plugs and I notice that the car runs much smoother and I also notice that it doesn't waste gas as it used to

 

Pull them out and check the gap, it's pretty easy to do. Your old plugs looked fouled out.

 

I saw on a forum that is not good to mess with the iridium plugs
