Seem ok so far. Hoping they make a horse power improvement & give me better gas mileage. Maybe to soon to tell. Chose these over AC Delco from the hype article. Hope I made the right decision. The right decisions made these days are even more important than ever. Was fast shipping, appreciated. Thank You. Hope to update this with better view soon after I drive with these plugs. Maybe I'm just to use to a V8. Still trying to get use to driving a car instead of a 4×4 Chevy Silverado. Quite an adjustment.
