I have a 2012 honda pilot with approx. 117xxx miles and have been thinking it may be time for spark plugs (bought with 92xxx miles and do not know the service history, i did already do timing belt service). I pulled one of the spark plugs to get the part number and it is NGK ILZKR7B 11. In my research the correct plug for a 2012 pilot is NGK DILZKR7A11DS - question is did someone already change the plugs in my car or is this an updated part? Also, i can still buy ILZKR7B 11 plugs considerably cheaper than the DILZKR7A11DS plugs but the websites all show incompatible with the 2012 pilot, is that true? The pilot does seem to be running fine and is getting approx 18ish mpg city and like 21-22mpg hwy (summer) - should i even worry about changing the plugs?
