Question how long should they last with normal driving conditions, I just replaced my 02Ranger's plugs at 92,000km's. I'm guessing the L will need to be replaced sooner witch is no big deal, just wondering when I should be doing them...

Thanks for the help!

kilometers? where do you live, europe?

i think the stock platinums are supposed to last a long time, like almost 100k miles. but i dont like platinum plugs, and if you mod with a pulley 4lbs and over then you will need to replace them anyways

 

LOL! No I don't live in europe I live in Ontario, Canada.

100k ok thanks.


haha

 

Regardless if it’s a Lightning or not I feel 100,000 miles is a long way to go before new plugs. I would at least pull them every 30,000 miles or so and check them to see what condition they are in. If you do leave them and not pull them till 100,000 miles and happen to keep the truck that long you may have one hell of a time getting them out. Just something to think about…
