First time using this brand
B. Jones1 month agoVerified PurchaseRecommendedI’ve always used AC Delhi because of my Chevelle. NGK is called for in my car(Toyota) and the last set of that brand didn’t last a year. I’ll see how long this brand will last. I’m not used to pre-gapped plugs, I prefer to gap the plugs myself but we’ll see!Purchased for: 2003 Toyota SolaraHelpful?
