You don't have to check the gap?

Hi Chuck, Great question! While many modern spark plugs come pre-gapped from the manufacturer, it’s always a good idea to double-check the gap with a feeler gauge to ensure it's within the recommended range for your specific engine. That said, given our experience and how often we work with these products, we’re confident in how they come and how they fit, which is why we typically skip this step. Thanks for reaching out, and feel free to ask if you have more questions! PartsVu Support Team!
