Spark plug Autolite or OEM Volkswagen

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.

In my 206 classes we run this autolite sparkplug because it’s required.

My understanding is that we switched because people were buying plugs in bulk and looking for ones with the lowest internal resistance believing it would effectively advance the engines timing. Supposedly these autolite plugs are much more consistent.

If you care more about performance, or cheaper cost, get the autolite a103, or ar103. Those will give you the best performance, but they only last like 10k. But they’re also dirt cheap.

I have autolite xp in the van. $100 for 6 ngk, $90 for denso with a van with 250k miles. Everyone says there crap, but it runs great.

after changing the spark plug for another autolite it stopped misfiring its still a little rough so I fear it may comeback so I just ordered some NGK plugs.

Make sure if you purchase spark plugs that it is not Auto Light. They tend to mess your vehicle up more and not work well with Toyotas.

The factory spark plugs are honestly shit in terms of longevity.

Don't use AutoLite plugs in this car, they are known to have issues.

Also, Autolite is extra terrible. I would have done anything else.
