In this Denso Iridium spark plugs review, we’ll take a closer look at their features and benefits to help you decide if they’re the right choice for your vehicle.

Finally, the design also helps reduce emissions by promoting complete combustion.

So how do these features translate into real-world benefits? Well, Denso claims that their iridium plugs can provide up to 30% better fuel economy and increased horsepower and torque. They also say that the reduced tip diameter improves ignitability, resulting in quicker starts and smoother idling.

In terms of emissions reduction, Denso says their plugs can lower CO2 output by up to 0.4%. Of course, all these claims need to be backed up by real-world testing. Unfortunately, there aren’t many independent reviews of Denso Iridium spark plugs available online.

However, there are plenty of customer testimonials on the company’s website that attest to the improved performance of these plugins . Based on this feedback , it seems safe to say that Denso’s claims are accurate and these spark plugs really do offer significant gains in terms of engine performance and efficiency .
