Review on 🔌 ACDelco GM Original Equipment 41-101 Iridium Spark Plug - Reliable Performance and Durability for Your Vehicle by Reid Rickerson

I have an old car here and it needs new spark plugs. Always noticed a slight push/pull feel in the hills. I thought about many things but in the end I decided that the candles will fall apart. Put new ones in and the car runs much better. Very smooth and no more bumps on hills. Even if your candles have been rated for 100,000,000,000,000,000,000,000 times, you can replace them sooner as you approach that date. We also manufacture plug wires. After I installed new spark plugs and wires all the problems went away. Makes me very happy. I am satisfied and highly recommend these AC Delco spark plugs. Sometimes they have good discounts!
