I've used the factory Denso iridium and NGK iridium spark plugs in my 03 Honda CRV and have always noticed that the idle would not be really steady after 7,000-10,000 miles; in addition, power requirements always requires me to dig a little deeper into the gas pedal around the same mileage (I am very sensitive to slight changes in power and idle rpms). With Bosch iridium I was getting gas fouling after about 10,000 miles to the point it would occasionally pop with a misfire on hard acceleration. By the way, my air filter is clean.
The Denso iridium tt spark plugs have been consistent from day one. The idle is rock solid, acceleration feels the same as the day I installed them and my mileage is great. Denso claims that I should get 100,000 plus miles out of these spark plugs. I wonder if this will occur?
