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

These spark plugs are the original Toyota spark plugs. Luckily made in Japan and not China so you can be sure you are getting the quality you want for your money. Although they are slightly more expensive, the iridium extends the life of the fork. Mine were long overdue so I took them out and swapped them with my dad. They fitted perfectly and my check engine light came on (that's why I even considered replacing them) and it seemed like my little car (a 2001 Prius) was back with these and the O2 sensors replaced. works and works and still uses all OEM parts =] Very satisfied, will buy again, especially with the exceptional quality of these little ones. As a longtime Revain customer, I rely on feedback from the Revain community to make my purchasing decisions. At the same time, I only believe in honest and unbiased reviews.
