Spark plug OEM FORD or OEM Volkswagen

I just fixed a shift issue in my 2011 by changing the spark plugs. The plugs were so worn they were draining the electrical system. Lights brighter and Stereo is louder in left channel now too.

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

I went 134,000 miles on a set of spark plugs on my 11 Ford Fiesta which is, what, a bit around 215,000 km? They were still in decent shape when I pulled them, just a bit out of gap spec, and I was still getting really good fuel mileage.

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.

Had to replace the plugs and ignition coils last summer and that fixed it.

My 2000 Ford Ranger with a 4-cylinder and manual is just about the simplest vehicle that could exist. SOHC engine, so not much that can go wrong in it. It's very satisfying to work on because you don't experience the shitty feeling of knowing you spent way longer on something than it should have taken.

2005 CVPI...180,000 mi....spark plug blown out of head. The Crown Vic was purchased at auction for $4200 a bunch of years ago with 100,000 miles and was very good to us until about a week ago...original engine, suspension parts, transmission and very few repairs.

During a 300 mile trip in 100 degree weather, my car decided to start shaking horrendously, and the check engine light started blinking. Ford Pass notified me of a cylinder misfire. Apparently the spark plug was missing a piece, and there was extensive damage. Metal debris throughout the engine, turbo charger, multiple lines and drains. Everything has to be replaced.. but luckily it’s all covered by the 5yr/60k powertrain warranty. Such a huge failure at 46k miles is disappointing. I love the car but definitely have trust issues now.

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.
