Review on 🔥 ACDelco GM Original Equipment 41-121 Iridium Spark Plug: Optimize Your Engine Performance by Sean Huff

I've driven my 2014 'bought new' Cruze about 90,000 miles and thought it was time to change the spark plugs. I've seen conflicting information on what spark plugs to get for this car. The original connector was a Delco 41-121 so I decided to stick with the same connectors. They fit perfectly with no issues with torque specs up to 18 ft-lbs. They are also pre-approved for the Cruze engine. Very easy installation. , just make sure you don't over rev and you'll be fine. The car works like new again.
