Assuming the noise is new and initially started immediately after replacing spark plugs, you've got the wrong plugs.
Or, if when you removed the plugs, some solid debris fell down into one or more cylinders. That is why you should ALWAYS use compressed air to blow out any and all debris from the spark plug wells before even putting a socket on the plugs. Oh, and yes, always wear safety glasses when using compressed air.
This advice is for any vehicle, any brand, with recessed spark plug locations.

Screwed into the engine. Follow the spark plug wires.
