Great plugs for the price. My gas mileage had dropped off significantly, lately. I was having an occasional misfire...trouble starting in the morning... All of the signs that a spark plug or eight were failing. So, After reading many reviews and checking my wallet, I decided on Denso Iridium spark plugs. I had been an AC Delco man, well let me tell you, these plugs are awesome. They come packaged, pre-gapped. (I know because I double checked them.) They have a plastic tube protecting the gapped end. And a box for each plug. I've only had them in about a week, so I can't comment on longevity, but the performance has been undeniable. I will definitely get Denso's for my 2nd car, when plugs are needed. I have received no compensation for this review, but I will happily accept 6 plugs for a Chrysler 3.8 liter. (You know...the 2nd car) ;)Nice plugs at a great price. Used these in my 1971 Nova 350 with Vortec heads. The thread reach is .708” so they fit perfect and the engine runs great.Worked greatThese are awesome, was surprised because of the price but they’re working great thus far. I’ll update if the crap out prematurelyThis were great replacements for my oem plugs. I put these on before traveling 2500 miles and my Suburban ran great. The price was right and I feel like these will last a long time. I've always been happy with Denso.Replaced the spark plugs in a 1996 Silverado with 289,000+ miles .. The Denso plugs provided a smooth idle and restored acceleration. Very pleased ..Great plugs.proper plugs for 5.3 ltr GMC V8 engine, disliked how hard they are to install even with the right tools!
