I have a 2006 camry I4 and I wanted to know what interval should i change the spark plugs? My older toyotas i usually just changed them about 30k but i have heard that the new engines the plugs last longer. I bought my car used and the previous owner was boob about cars. Of course the dealer close to me wants to know the mileage before they answer to make it sound legit when they tell me i should change them.
Can some one tell me the official interval?
Thanks
