Spark Plug-Eng Code: B5254T4 DENSO 3421

Great Plugs

Designed to fit my vehicle, easy to install, and, being iridium, should work perfectly for 100,000 miles or more. Denso quality is well known, and is what Toyota installs in my vehicle at the factory.Read full review

Iridium is the way to go

Great quality. Not sure why Toyota uses regular steel plugs.
look at my Toyota installed plugs after only 30K miles, all burned down.
The Iridium are rated at 100K miles.
