Review on 🔥 NGK #1465 Laser Iridium Spark Plug IZTR5B11 - Pack of 8 Units - Brand New by Jamal Gignilliat

My 2001 Chevy Silverado LS (5.3L) needed new spark plug wires and the ACDelco Professional Platinum spark plugs on them were outdated so I decided to replace them as well. These new NGK Laser Iridium Plugs are fantastic. I've noticed a slight improvement in fuel economy and the engine seems to run smoother. I usually avoid aftermarket parts for my car, but NGK has a long track record and I enjoy using their products. It's definitely an improvement over the old worn out plugs I used. Remember DO NOT apply anti-seize to spark plugs, they are coated at the factory and do not need an additional coating!
