Review on ACDelco C88L Specialty Conventional Spark by Kyle Pickett

The plugs I received are NOT the ones pictured. These are C88L but they (the ones I have) DO NOT have a knurled area between thread and hex nut area and SHORTER. The extra length is needed in some cases, like my Case tractor. I could handle those shorter spark plugs because I had a thin-walled spark plug wrench from a motorcycle tool kit. If I didn't have this special wrench, I wouldn't be able to tighten the plugs and would have to go through the hassle of returning and ordering a new one. I would also TICK correctly. Because I am not satisfied with the service.
