2000 Ford F-150 Lightning Q&A
2000 Ford F-150 Lightning Question: spark plugs
What is the best spark plug for my truck I have heard horror stories about 3 valve motors but mine is two but would like to know which plug is the best for me. thanks - Visitor
stick with the original equipment plugs. autolite or champions are fine. roy - mastertech6371
Agree with Roy, important to add a dab of "Never seize" to the thread of the spark plug to avoid the plug seizing in the cylinder head in the future. - patrick mannion
Our technicians tell us the spark plugs in this engine can be very difficult to remove. Ford has issued a service bulletin (08-7-6)...
...due to excessive spark plug gap. To fix this problem, the ignition coils that have failed, the spark plugs, and all coil boots should be replaced.
Seriously...tick showed up a few days ago. Never been raced, in great shape, all original. New head earlier this year. Now they are telling me I need a new engine. Has 110,000 miles. Any sugge...
