Review on Denso SK20R11 Iridium Spark Plug by Vic Alexander

Factory and brand new - perfect. Not used to that little spark plug but according to the specs and what the big boys say they should last at least 100,000 miles with no problems. The fit and finish is perfect and they went into the auto split with no issues. Now I'm a happy driver. I also ordered a 5/8" twist rosette to install and this is a cat meow for this setup with these connectors. Update 30th August 2015 I must add that I have experienced an increase in fuel economy of up to 3mpg on my Toyota since it was fitted. Also with these plugs the engine starts easier and quicker and runs much smoother. I will never again use another brand of spark plugs for my camry!
