There was a previous ticking noise, it's now louder after replacing spark plugs. The new spark plugs are shorter on the white part, if that matters? But the threaded part is the same length. The car has coil packs instead of wires, if that matters either.
Ticking gets louder and faster during acceleration. It doesn't go away once the engine has warmed up. I also replaced the intake manifold gasket at the same time, if that could've worsened the issue.
