Spark plug Motorcraft or OEM Volkswagen

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

I replaced the spark plugs, ignition coil plugs, alternator and checked the tensioner.

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

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

FWIW, I just had spark plugs and coil packs done on my 2016 Jetta, $185 out the door at my local dealership

I had a 2012 Passat I drove for 10 years (after buying used with ~20K miles) and only just replaced two weeks ago with ~125k miles. I had to replace the alternator at one point and some other general stuff like spark plugs over the years, but that was it really. Nothing super expensive.

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 done an oil change as well as swapping the spark plugs and coils for brand new ones. The roughness persists!

I just came across a recent problem while doing my spark plugs at 80,000 miles. The dealership was the one that did my spark plugs at 40,000 miles. Sure enough, they broke Cylinder 3\u2019s wiring harness connector to the coil pack and stripped the bolt. I had to helicoil the bolt, replace the connector, and repin the connector.
