does anyone have the part# or pics of your denso iridium plugs in your 3.0 motor? i want some for my truck but need the part number.

they have all the part numbers and everything you should need.

 

What kind of difference to Iridiums make? What applications would people recommend them for?

 

Iridiums act just like copper plugs, except they last a long time and are very efficient. In my opinion, nothing beats copper in terms of reliability, performance, and cost. Iridiums sure cost a lot, but they are worth it in the long run and they sure as hec last a long time. I'm still using mine after 2 years.

Stay away from Bosch plugs on Toyota applications.

 

thanks, that was perfect

 

glad i could help.
