What should I know before installing the UF742 coil pack?

Installation is straightforward for anyone comfortable with basic engine access and hand tools, but check a few items before swapping coils. If multiple cylinders are affected, inspect spark plugs and wiring boots since coils fail more quickly when mated to worn plugs.

• Turn off engine and disconnect battery before starting
• Check and replace spark plugs if they show wear or incorrect gap
• Confirm OEM part numbers and engine application prior to purchase
• Clear stored trouble codes after installation and verify repairs with a test drive
