Review on Enhance Performance with Denso SC20HR11 Spark Plug by Jim Kriegshauser

Revainrating 5 out of 5

Do not change replacement spark plugs when the engine is hot, wait until it has cooled down.

OEM, at the moment I've clocked 125,000 miles on my 2010 S Corolla and noticed that the engine is shaking when you turn the engine on so I've replaced the same spark plugs, hopefully for hundreds more miles to come.

Pros
  • This is amazing
Cons
  • functionality
