Review on 🔌 Denso SK16R11 Iridium Spark Plug - (3324) - Enhances Engine Performance - Pack of 1 by Mike Sutherland

These are the best spark plugs you can buy if you own a Toyota. I had misfires with my old spark plugs. The candles were only 4 months old so shouldn't have caused any problems. They were supposed to be Denso SK16R11 plugs but I bought them from another seller thinking I got a deal. Boy was I wrong. I ordered another set from Revain (seller) and noticed the packaging and plugs look different. Both were marked Denso SK16R11 but looked different. The new set worked great. From now on I only buy from authorized dealers.
