Review on ✨ Enhanced Search-Engine-Optimized Motorcraft SP-493 Spark Plug by Roberto Tucker

They should come with a pre-gap of around 0.054-55, some had a slightly higher gap, always check. Used them on my 2005 F150 XL 4.6L. They fit. The torque spec could be as low as 16-18 but I bumped it up to 19-24 just to be on the safe side because I've heard that a small amount of thread could push them out of the motor but I have not done it. haven't had any problems so far. When these stubs were removed earlier, they were easy to remove.
