Spark Plugs - NGK Equal?

[McFly121]

I'm glad you found the post helpful . Factory torque spec is alledgedly 12ftlb. However, being an aluminum head it really depends on the temperature of the engine when you swap them.
If your doing it cold I'd recommend the 12ftlb +/- 10-15deg. If you use the 12ftlb with the motor hot the ceramic on the plugs will likely break when pulling them out.
How's it been running? Do you have any bolt-ons?

So what your saying is on my 2020 ill be fine doing 10-11 ft/lbs on my new plugs..get so many different answers different sorces

I used NGK Iridium in my old Sport Trac. For the Ranger I stepped up to NGK Ruthenium on the advice of a guy on another Ranger board who owns a tuning shop. Mine isn't tuned so I stuck with the stock heat range. Runs great.

Despite In ngk thread I did go oem. I'm just going to probably go between
11-12 ft/lbs seems to be a good range
