DENSO makes a spark plug for every personality – from 100,000 miles to 150+ mph!

Welcome back! Let’s continue our look at the world of DENSO’s spark plug innovation. This week: Why DENSO?


When it comes to gasoline engines, nothing happens until there’s a spark! And to keep your engine running smoothly, spark plugs fire 25 times a second – or more! If just one spark plug skips a beat, you’ll know it instantly with rough running, poor acceleration, and reduced fuel economy. That’s why you need DENSO spark plugs – each one is designed to deliver the right mix of performance, economy and durability. Plus, every vehicle is unique, which is why DENSO produces a wide range of spark plugs that are the perfect match to your vehicle.
