Anyone use denso TT spark plugs?

Anyone use denso TT. Spark plugs in the truck yet? Curious about if it does help with mpg

 

Sorry to rain on your parade but the only way a plug will improve your MPG is if the old plugs are severely degraded and have hurt your mileage. No plug will improve your mileage beyond what it was when new. Iridium plugs just tend to last longer in the job due to using a better material for the electrodes and for that I like them.

 

Im always curious about these reputable companies making such claims. Just wondering if anyone actually has installed them.

 

I think the way they are able to make that claim is because in the fine print it will state that it improves MPG vs. worn plugs.

 

With Cafe rules if improving MPGs were that easy it would be fine at the factory. I dismiss any claims for improved MPGs except tires.
