Bigger Bang for the Buck
May seem that these plugs are expensive. This is my 4th set through the years. And every time, they prove their value in better gas mileage, quicker acceleration, and lasting longer than conventional or platinum plugs. This last set replaced the factory iridium plugs in my 2015 F150 5L V8. Have observed an increase in overall mileage from 17.4 to 19.2 MPG. One can feel better acceleration immediately after installation. A previous set was installed into my 25-year old, V6, 2-cycle, outboard motor, which has historically needed replacement of conventional plugs every couple of years, at best. The Denso Iridium's have lasted now into their 4th year with no signs of fowling, not starting quickly, or not running smoother and with more efficiently than with conventional plugs. Have already purchased another set for my new BMW, just because I know I can count on better overall performance created by a 'bigger bang', easily outweighing the 'buck' or cost I had to pay.

Did a very good cleaning job!
Apart from being unable to stabalize the temperature as set, was able to compensate and realize a very good cleaning process.
