Having problems with your 2003 Toyota RAV4 ?
Spark plugs When is the right time to change spark plugs or how to identify bad one?
Stock spark plugs are usually good for 100k miles. if you pull one out and there is aot of gunk built up on them or they have a lot of carbon on then i would change them. but generally if your car has less than 100k miles then youre ok. after that id be changing them with stock replacements only. dont go for cheapies or the latest trend. if it calls for ac delcos then buy those and so on.
