Perfect for my 2021 Ford F150 5.0
I recently installed these spark plugs in my 2021 Ford F-150 with the 5.0 V8, and I'm thoroughly impressed. They seamlessly matched the OEM specifications and came pre-gapped, which was a convenient touch, although I made sure to verify the gap myself — a step I'd recommend to anyone. The new plugs immediately resolved a minor misfire issue, a significant improvement given the extensive idling I do with my truck. While I haven't monitored the fuel economy closely, the overall performance boost has left me very satisfied with this purchase.
