Shelf life of spark plugs Hey all, I just have a quick question. When I put my headers on about a year and a half ago, I bought new plugs to put in the car. I ended up forgetting I had bought them when we put the headers on, so I still have them sittin here. They are the NGK tr55's. Im having a cam installed this next week or so, would my NGK's I still have sittin here at home still be good to put in when I have the cam installed? I dont really see why they wouldnt be bad but Im not positive. I dont have a problem buying new ones, just curious. Thanks guys.

there are people with NOS plugs from the early 1900s that are still good... lol
they dont go bad, they're just a couple strips of metal and some ceramic.... the only way they can degrade just sitting there is if they're in a corrosive environment.
as long as the ceramic isnt cracked, and it isnt corroded, its good.

Thanks guys, I didnt thnk so but just wanted to make sure. They are still in the box that they came in sitting in my room so I know they arent corrosive. Im takin my car friday to have a cam install done giving them the new plugs with it along with my new 160 t-stat that I just havent got around to installing yet.
