Spark plug Bosch or Motorcraft

To be honest the last plug VW went with , the 101905601F (OEM clones Bosch copper nickel FR7HE02 Or NGK ZFR6T-11G (5960) Copper Nickel, Beru BRU-Z272 copper nickel ) for the 2.5 is best. It’s one shade cooler and will have less spark knock. You have more timing.

I ended up leaving them as is and the car seems to be working fine.

As long as the Bosch ones match the factory specs then I’m sure they are fine as many other parts and sensors on these cars are made by Bosch.

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).

i bought ngk plugs and bosch platinum triple diode plugs and i got the coil pack off ebay.

I got misfires with FD5POR RS2 plugs. Almost 10000kms on Bosch f2cs this year. Been working perfect for me

Long story short: changed spark plugs 4000km ago as per my 2019 Hyundai Kona 1.6t manual. Followed Service manual, and the recommended torque on the side of the box of the Bosch (non OEM) replacement, 17 ftlbs.

Grounding electrode on plug #3 failed, destroying 2 valves and marking up the cylinder wall.

I just put Bosch plugs in my 13 Veloster turbo and got 300 miles and it started missing replaced with the ngks no issue since

Do not I repeat do not put Bosch plugs in any import. Don't know why but they always cause problems.
