Can someone advise what spark plug I should be using for my 2018 Ford -F150 5.0 ?
I have 65,000 miles on the engine and would like to have spark plugs ready to change out before I start removing them.

thanks in advance.

I'd use OEM. Part number is listed on page 423 in the 2019 manual

 

Would you happen to have the spark plug #. ?

 

Plugs are not needed until 100k. 2018 5.0 Spark Plugs - Ford F150 Forum - Community of Ford Truck Fans

 

True unless you're towing then 60,000 miles

 

SP-551 for a 2019 5.0L

 

I have a 2018 and I pull a small camper during the Spring- Fall

 

Is that equivalent to CYFS-12Y-T6 ?

I think that was superseded by SP-589. There's also SP-588 which is supposedly better for towing and severe service.
