I want to try denso in my car for a change. Which would you recommend? Denso iridium power (ik20L) or Denso iridium twin tip (ik20tt)? Gap is 44 and 40 thou respectively.

 

Anyone??????????

 

We've run Denso IK22's (#5310) since new in our GD. They are one heat range colder than stock and come gapped at .032" which is better in my opinion. Picked up a little power.

 

Thanks for the reply. I’ve read a lot about the famed IK22s but I’m a little concerned about performance in the winter though. In montreal we can go as low as -25F on the absolute coldest nights. Still ok for starting in frigid weather?

 

I truly wouldn't know. We just don't get that cold.

Bright side with a GD Fit is that the plug change is a few minute job. Can give them a try.

 

Twin tip lasts longer than iridium power, if you want the longest life possible, get the Denso Long Life or NGK Laser they are both stock/oem.
