      No Change, but hopeful

      6 of 7 people found this helpful

      I've installed these plugs in my 07 Mercury Mariner Hybrid at 100,000 miles which was 8k miles ago. The factory plugs didn't seem bad when i switched them out. I was worried from previous reviews of this plug stating you'd get worse mileage from these plugs somehow. I was assured by an Autozone employee i'd get much better mileage. Neither one happened. I've noticed no change in mileage or performance which is disappointing. This is also coupled with a new fuel filter, air filter, and oil change. The biggest positive change I've noticed in achieving higher gas mileage and performance is using a higher grade gasoline. So these plugs remain neutral to me, but i'm hopeful they'll keep the Mariner running strong for years to come. I'm just glad I've purchased these during a rebate period for cheap, otherwise my review might be more negative. I'd recommend this product if you're installing them in a sports car (which might yield better results) or if another rebate pops up.

      Pros: No negative effects, plug has potential for performance

      Cons: No positive effects, higher priced for no change
