Delphi Vs Denso Ignition Coil: Major Differences

I’ve discussed the distinctions between them, so let’s explore something more interesting.

Fuel Efficiency

Both ignition coils make your horsepower go up, like their original parts. But when it comes to deciding which one is the best, Denso ignition coils make your horsepower SUPER high for your Mazdas, BMWs, and more. And Delphi ignition coils can especially give your SUV or truck an extra boost of horsepower.

Quick Start

An ignition coil is like a powerful charger – it takes the low current from your car battery and converts it into an even more powerful spark that’s capable of starting up your engine. When comparing Delphi to Denso, you’ll find better results with Delphi but if you have a lightweight vehicle then go for Denso.


Denso is like the Energizer Bunny of ignition coils – it just keeps on going and going. On average, an ignition coil lasts 100000 miles. But Denso’s can go up to 240000 miles, which is more than double that amount – while Delphi only has 40000-mile lifespans. Pretty impressive stuff from Denso.


Both the Delphi and Denso ignition coils provide a reliable performance that can be relied upon. The Delphi coil offers a more cost-effective option and is great for those on a tight budget, while the Denso coil offers higher quality and more reliable performance that can be relied on. Ultimately, the choice of which ignition coil is better is up to the user, and both Delphi and Denso have several models to choose from.
