Review on Autolite XP25 Iridium Spark Plug by Evan Popal

I purchased these spark plugs for my automotive needs since I read positive reviews online. Thanks to my knowledge gained in PRACTICE, i can confidently say that this product is a total waste of money. The spark plugs failed to perform properly and caused my engine to misfire. The only positive aspect of these plugs is their longevity but that doesn't matter if they don't work properly .I would advise against purchasing these spark plugs and instead invest in a different brand..
