Click when shutting off car

[MrWright19GT2]

Hey guys, was wondering if this clicking noise was normal coming from the engine. I just did my spark plugs and now when I cut her off there’s this strange almost single loud click. Any info would help. Thank you in advance! I’ll get a clip right now.

well if you just did your plugs and you have a noise when you turn it off something's not right
