Review on Denso SK20R11 Iridium Spark Plug by Viswanath Badasz

Revainrating 5 out of 5

Denso gets the job done - ignition parts

I installed (March 2016) Denso SK20R11 iridium spark plugs on my 2005 2.4 liter Toyota Camry XLE. I bought a new car and after 110,000 km I wanted to change the spark plugs. In the process I broke two (2) plastic wire harness retainers. I used masking tape to keep them from falling apart. I used my air compressor and cleaned out the dust around the coils and in the spark plug chamber. After a lot of reading and debate online I decided not to use EP for the threads and tightened the new plugs to 14 ft-lbs. The plugs were already full. My old Denso spark plugs showed minimal signs of wear. However, after installing new spark plugs, I think the engine ran smoother, quieter, more powerful and improved gas mileage. It was an easy job and the plugs arrived quickly.

Pros
  • Availability
Cons
  • Makes me angry
