When you choose NGK spark plugs, you're in good company. Automobile manufacturers around the world recognize our unsurpassed quality, reliability, and performance. From leading Japanese makers like Honda, Toyota, Mazda and Nissan to domestic manufacturers like GM, Ford and Chrysler, NGK spark plugs are already onboard when you purchase your new vehicle. But the global confidence in NGK quality doesn't end there: Volkswagen, Saab, Audi, and BMW also specify NGK spark plugs as new and replacement equipment. So does Rolls Royce, Jaguar, Aston Martin, Maserati, Alfa Romeo and now Mercedes Benz.
NGK's attention to performance excellence sparks that kind of commitment. It's what has made NGK the world leader. From our technologically advanced racing spark plugs and cold performance Iridium IX line, to our economical OEM quality replacement plugs, NGK is the spark plug of choice for millions of drivers. It's the same for non-automotive uses. Small engine manufacturers like Briggs and Stratton, Polaris, Bombardier, Yamaha, Kawasaki, and Toro all depend on NGK quality for their power plants.
