No plug torque is printed, so this page does not call for a torque. The gap is a specification, not a removal procedure.

Firing sequence from the 2017 Fusion owner's manual engine specifications. Sequence only.
Illustration, not to scale; confirm with your owner's manual. This is the firing sequence only. It does not show where each cylinder sits on the engine.

1.5L is 0.025-0.029 in. 2.0L is 0.027-0.031 in. 2.5L is 0.049-0.053 in. 2.7L is 0.028-0.031 in.
1-3-4-2 on the three four-cylinder pages. 1-4-2-5-3-6 on the 2.7L page. The drawing below is that sequence and is not a picture of the engine.
The parts note says to contact an authorized dealer. Normal interval is 100,000 miles. The severe charts that name towing, long low-speed driving, or dusty roads say 60,000 miles.
Drivebelt figure numbers sit on the same specification pages. They are described on the drive belt guide and are not redrawn here.
The 1.5L schedule also names a timing belt at 150,000 miles. That is not a spark-plug interval and it is not given a procedure in the text that was read.
Outbound links only. BaySheet does not sell parts. Confirm fitment on the retailer page. Amazon links are searches for a real part name plus this vehicle. Tool rows do not get a product search. The search is not a part number.
