Review on 🔌 Pack of 4 Autolite HT0-4PK Platinum Spark Plugs with High Thread by Marco Habersham

Let me start with the positives first - AMAZON stood up and took care of the problem. As for the product, it's absolute rubbish. I bought a set of 8, out of 8 2 fell out right out of the box! That's 25% bounce. I contacted Autolite and explained my diagnostic method and the tech agreed the spark plugs are BAD but then they want you to send them back for 2-3 weeks for analysis. Those that failed gave out misfire codes immediately, and in one the porcelain actually came loose after removal. Like I said AMAZON has stepped up but Autolite makes junk so watch out.
