Changing spark plugs
Hello all, I have 71k miles on my 08 and I decided to check the plugs. The two plugs I checked have rounded electrodes and a .055 gap. I know the recommended mileage is 100k but I have decided to change the spark plugs. I am considering NGK Iridiums. Alot of people recommend staying with the factory Champion double platinums, but I'm wondering if anyone has run the NGK iridiums without fail. I have generally owned Toyota vehicles in the past and NGK plugs work excellent in those. Thanks in advance.
