ngk are better than OE m8
Thats better than i thought. i know its ngk and bosch are the top brands bosch are way too dear the universal ones are a waste of money. I seen one of your postings saying they affect mpg i already have a major improvement consumption was around 20.7 mpg before right now its at 23.9 a big difference. and when funds allow i will get the second sensor replaced
