Best plugs for most all stock applications.
Always go with the best plug for your application...Denso is factory quality and never disappoints! You don't have to worry about it being too hot or too cold of a plug for your vehicle. I've always used it in my Toyotas, and run them for 100,000 no problem. No fouling or missing.

HIGH QUALITY spark plugs!!
I'm a simple guy. I see Denso, I purchase. Car accelerates like it's new, ignition is super, and I expect to see them perform well for a long time.

So far so good
Replaced all four ignition coils and plugs on my 2015 Toyota Corolla LE after a misfire in cylinder 3 caused by a bad coil. It’s been a month now, and everything is running smoothly. I’ll update this review if any issues come up later.
