Replaced along with some bad ignition coils
My 2017 Kia Forte was throwing out ignition error codes, so I replaced all the ignition coils and spark plugs. They arrived quickly, seem to be of good quality, and installed as expected. This happened about two years ago, and I have not had any issues since, so I would say that they are performing well.

Honda Pilot plug
Wife's car has 130k miles. I've never done anything on it but its been very reliable. Decided I need to start doing some PM and this was part. Old plugs didn't look too bad, but these couple with a transmission/PS fluid change and some fuel injector cleaner has the car running like a champ.

Great product
Arrived in brand new condition sealed nicely. Perfect fit and OEM spec for 2016 Kia forte sedan. Great price verses auto parts store and much faster shipping than rock auto.

2013 MINI Countryman
These fit on my 2013 mini but withbsome work arounds. You need a 14mm thin wall socket to remove the oem ones. However these plugs are 6 pt 16mm. So you have to lower them with the 14mm socket to get it started then tighten with a regular 16mm socket to tighten them.
