As a seasoned shade-tree mechanic, and life-long electronic technician, I've worked on countless Toyotas, and I've consistently noticed one thing: they all come equipped with Denso Iridium spark plugs. After numerous installations and inspections, I confidently give these spark plugs a perfect 5 out of 5 stars for their outstanding performance and durability.Denso Iridium spark plugs are engineered with precision in mind, featuring a fine wire iridium center electrode and a tapered ground electrode. This unique design helps to improve the efficiency of the ignition system, leading to smoother starts, better fuel economy, and a noticeable improvement in engine performance over the lifespan of the plugs.One of the most impressive features of these plugs is their longevity. They live up to the promise of lasting 100,000 miles, making them an exceptional value for the price. For vehicle owners, this means less frequent replacements, reduced maintenance costs, and the peace of mind that comes from knowing your engine is operating with one of the best spark plugs on the market.I also appreciate that Denso Iridium plugs produce stable combustion during the lifespan of the plug, contributing to the consistent performance and emission reductions. This aspect is crucial for keeping vehicles running optimally and passing emissions tests without trouble.If you're looking to replicate the original performance of your Toyota or simply upgrade your current vehicle's spark plugs, Denso Iridium is an excellent choice. Whether you're a professional mechanic or a car enthusiast looking to do some DIY maintenance, installing these spark plugs is a straightforward process that yields real benefits in terms of engine response and efficiency.In summary, if you're in the market for reliable, high-quality spark plugs that offer professional-grade performance and longevity, you can't go wrong with Denso Iridium. Highly recommended for keeping your vehicle running smoothly for miles to come.

My wife and I each drive Toyotas. We took her car in to the dealer recently for routine inspection / maintenance. They charged $26 EACH for the spark plugs and $200 to install. My car (2010 Toyota Yaris) was also due for maintenance, but there was no way I was going to pay $300 again just to change spark plugs. These Denso plugs are perfect, about $35 for the set of four, and took 45 minutes to install. Car runs great, and I'm happy saving a fair bit of money!

Great spark plugs! Fixed the vibrating the bad ones were producing i.e. engine stopped vibrating right after upgrade. Purchased these for a 2007 Toyota Yaris Hatchback.

I have serious doubts about the authenticity of these spark plugs as genuine OEM Denso products. The specified gap for these plugs should be 0.044", but when I measured all four, they ranged from 0.041" to 0.043". On top of that, the threads on all four plugs appeared damaged or stripped, indicating poor machining. One plug had corrosion on the electrode tip, while another showed discoloration and flaking on the terminal tip. I was so concerned about their authenticity that I brought them to my local Toyota dealership, where a technician confirmed that they were not authentic. Given these issues, I would strongly advise against purchasing or installing these plugs in your engine.
