with my high milage cx 5 that has never been treated with this type of product or similar , i also did not believe my self until i tried it and i can say it was money well spent 😁. You should give it a try also. 👍🏼👍🏼👍🏼
Are your sure the plugs you ve bought are Genuine. If your car were running fine before replacing the plugs .. then it could be the New Plugs it self that are the problems because there are so many counterfeit plugs all over the interwebsz . Show us some photos of your new plugs vs old plugs.
I think it will help some owners and they will definitely need this info. So you won’t get fooled by an AC technician. As these small parts commonly fail in all our cars, they’re relatively cheap to replace. Better than not knowing what to expect, know what I mean. 😂😂
I think the OEM Mazda ones are branded NGK just with Mazda Stamp branding on it . Well anyways i replaced my original mazda spark plugs with Denso Twin Tip Iridium they works excellent no issues & great for value.
