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.

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

My local advance didn't have 6 of the NGK's my Honda calls for, so I opted for these to see how they would do. I have to say, I have not noticed a difference between these and stock. I have put about 150 miles on my vehicle and it's running great. All plugs were pre-gapped to the spec and required no adjustment.
Bottom Line Yes, I would recommend to a friend
Pretty nice

I bought 6 last week. Early this week my car light up the engine sign. I returned to the mechanic and two of the spark plugs were already damaged. I went to a Ford dealer and bought 6 original spark plugs. I lost my money in Advance.
Bottom Line No, I would not recommend to a friend
This is only good for a temp fix

NkG is far more superior to this plug. I have them in and you can feel a slight misfire as I only needed one plug.
Bottom Line No, I would not recommend to a friend
