I'm wondering if there are any special spark plugs that actually save fuel economy. Ive seen the E3 spark plugs... Also, what O2 sensor brand is the best? I was thinking about replacing mine.
Is SNG a good 02 sensor manufacturer?
 
I would stick with regular plugs. You will not get the money back for the other ones via fuel mileage. As for the 02 sensor, Bosch makes a good one.
