Spark plug Motorcraft or BERU

Oem Motorcraft plugs are always my go-to. They generally last around 80k miles.

Modern Ford engines tend to work best with Motorcraft or NGK spark plugs.

use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.

Motorcraft is all I use , heard to many stories about aftermarket plugs causing misfires

I do run Motorcraft plugs because they seem to crack a little less than the Autolites.

anecdotally, my truck was at 226k when i changed the plugs. motor craft plugs coated, no anti seize, torqued tighter than advised. probably 20lb ft. 2 rear plugs were originals. i’m now at 235k and nothing wrong yet.

I’ve found that Motorcraft platinum spark plugs work best in my 1998 Ford Ranger. I tried Bosch plugs and it ran terribly. Nothing but Motorcraft from now on (for Fords).

Had these Beru plugs put in last year. Are they the kind that’s at greater risk for damaging the engine?

I ran Beru RS7 plus which are one step colder when I tuned stage 1 and they didn't last at all. Might have been under 10,000 miles. Recently went with NGK plus that APR reccomends for stage 2 and so far so good. No misfires since.

Iridium plugs suck on fords.
