these are the same exact plugs i replaced in my toyota tundra fo the 100,000 mile maintenence, the old plugs still looked good, so i knew it was a small price to pay to get another 100,000 out of these plugs. extremely happy.

Stick with DENSO !
I took out some high end high voltage race plugs that failed and went back to OeM Japanese plugs and the ignition coils. Some things you cannot improve like OEM !

Denso has never let me down
I try to buy denso when I can't buy factory oem parts. when it comes to Japanese cars denso is often who makes the parts for the factory. plugs work fine and have been working fine for anout a year now. im very happy with them.
