Superb performance for less money.
This is the second set of these I have used in my 2017 Subaru Forester 2.5i, this time stretched to 76000 miles but only did them again because Subaru calls for 60000 interval. The prior set had no issues, the new set demonstrate excellent performance and gas mileage. Recommend light coating anti-seize on threads for easier future removal.
Most Liked Negative Review
Not good for a 2007 Nissan Altima 2.5L
I put them in a 2007 Nissan Altima 2.5L and the car ran terrible. I ended up putting the old ones back in and the car is running fine. I am going to pick up the NGK dilkar6a11 . The part that sucks is I am out the money I paid for these, because Advanced Auto Parts does not take back spark plugs that have been installed, even though they are the ones that recommended them
