Review on 🔌 Denso (3247) Double Platinum PKJ20CR-L11 Spark Plug, 1-Pack by Paul Rose

I don't know about the quality of this product. All I know is that I took it to my mechanic and he didn't laugh in my face, roll his eyes or make an audible sound of disgust when I asked him if he could use it. I also trust my mechanic to tell me if I'm just giving him crappy gear and he will actually recommend something else. Maybe I should have just asked him for recommendations on what to buy first, but I'm too impulsive when it comes to annoying things like logic. I saved a few bucks on an already expensive auto repair and my car runs better.
