Always get it for my Toyota Corolla and works great!

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!

Good product and low cost.

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.
