Spark plug Autolite or OEM Volkswagen

I’ve had an APR stage 1 ECU tune on my 2017 GTI since 2020 with zero issues. I don’t track it. Just change plugs every 20k miles and have VW use OEM plugs.

I've been running autolite in pretty much every domestic that comes through my shop for years since they’re usually the workhorse for Ford and GM tunes. Also, I haven’t seen any dip in the plug quality lately so that's a good sign. The iridiums are still pulling clean gaps right out of the box.

I changed the spark plugs in my nieces 2.5L VW Jetta because it was idling at 1300rpm. Rock solid idle at 700rpm afterwards. Easy way to save some gas.

Changing the spark plugs, spark plug wires, ignition coil and the coolant temperature sensor fixed the cold start issue.

These are OEM plugs without the VW branding so cheaper, I run these in my stage 1 Mk7 GTi and they are good just need to gap them down quite a bit as out the box they are I think .32? I change them every 15,000km or every 2nd oil change

It\u2019s true that you dont\u2019 get quite as good performance as with the Bosch, but this is my second set of autolites and I\u2018m over 200k miles already.

Dont use autolite garbage, this isnt uncommon with cheap plugs. Get NGK Iridums

Pulled the spark plugs and #3 has burnt away the centre electrode. Plugs aren't all that old. Plug brand is Auto lite. Any ideas on what may be the cause?

A quick search shows that autolite spark plugs don't seem to perform well in modern vehicles, you might have to go for a higher quality closer to OEM quality plugs.

Homie, do not run Autolite plugs.
