flukey-lukey Posted March 3, 2009 Share Posted March 3, 2009 I've had my denso iridium IK22 sparkplugs in the car for 16,000 MILES (nearly 3 years) and I'm just debating wether or not to change them to new ones while I'm doing the valve stem seals. In the spark plug guide on here it says they're good for 30,000 MILES + So, change them or not? Link to comment Share on other sites More sharing options...
AlanM Posted March 3, 2009 Share Posted March 3, 2009 If you are having no problems with them I would leave them Link to comment Share on other sites More sharing options...
flukey-lukey Posted March 3, 2009 Author Share Posted March 3, 2009 No, no problems when the car was last used. I was just going to change them as a peace of mind thing until I read they should be good for more than 30k miles and I'd only done 16k Link to comment Share on other sites More sharing options...
AlanM Posted March 3, 2009 Share Posted March 3, 2009 I bought a new set about two years ago and decided to wait until I started having a problem with the set that are in but they are still fine, about 33k so far Link to comment Share on other sites More sharing options...
