Review on 💥 High-Performance DENSO # 5325 IRIDIUM Power Spark Plugs - 8 PCS Set - IT16 by Mike Morris

My 2006 Suburban 1500 5.3 V8 (the 'good' 5.3 from last year!) is about to clock 200,000 miles. Although it still works fine I figured it was time to change the spark plugs and wires. I was happy to find these Denso Iridium spark plugs that fit and they fit really well! The plugs came with a pre-gap but I checked them anyway and as expected they were almost in place. Although this is my first set of Denso's in my Suburban, based on past experience I expect them to last quite a while. I just installed them so it might seem a bit premature to give 5 stars for mileage and durability, but this is a Denso!
