Default LS460 Spark Plugs

My owners manual says to use Denzo Iridium sparkplug on my car.

I work for NAPA in Retail sales. Frankly, Denzo Plugs are not our top of the line plugs. NGK and Bosh plugs are higher rated.

I've never had a problem with Denzo Parts. At the same, I'd like to know what other owners use. Your input would me most appreciated.

Toyota/Lexus uses both. They'll have one bank be Denso and one bank be NGK from the factory.

The plug the 460 uses is a triple prong version that technially only Denso makes, I've seen NGK works fine as well but if you are trying to 1:1 use what it was designed for use the denso

Since you get wholesale pricing, just get them from Lexus. Save you headaches down the road.
