Review on Denso IW16TT Iridium Spark Plug by Brian Cheney

Revainrating 5 out of 5

Pickup Toyota 1988 22r

Exactly what you pay for! I replaced the old copper cores in my 1988 Toyota 22r pickup with these. I know they are for cars with reverse spark but I get cleaner cylinder flames from them and they should survive the truck now even though it's a brand new engine. I say this because there is no reason to replace such a spark plug after 120,000 km, the tip is so good on both sides that if it fails at all all you need is the gap at the plug. It can survive porcelain

Pros
  • Spark Plugs
Cons
  • Hard to say
