After wrestling with my 05' f-150 , which i recently traded in for an 05' expedition. I want to be proactive on the whole spark plug issue. My f-150 had 120,000 miles and i broke off two plugs and fought the rest!!! So knowing this going into the expedition I knew the first thing was to check the plugs.... pulled one today and they are the originals... did'nt look to bad and came out easy enough , truck is running great , 89,000 miles . So here is the question do i change them now or wait, and i see everyone says stay OEM, but is there any other alternatives. Or just anti -siez them and hope for the best next time around..... thanks for any help.....
