FedEx is delivering my Denso's today and I will try to take as many pics as possible and also report the changes I've noticed after installing them. My car has about 80K Miles so I figured it's time.
On a side note, a lunatic friend told me that the denso's have small tips and this way they will not work properly with the car or something like that. Obviously everyone on this forum liked them so I'm ignoring him but just wanted to throw it out there. |

The atomic number of Iridium is 77. I know it has 77 protrons and 115 neutrons. Other than that I cant tell you much else about it. Unless you want to know its Oxidation states and its heat of fusion. |

Hahaha. I think I saw a kryptonite set on ebay for $20 shipped.
I believe that my friends objection was with the gap of the Denso plugs which is .032 and the factory gap is like .052 or something. There is no reason why you couldn't gap them. |

Changing plugs in the 3.6 is major surgery. Not a DIY for many.  |

I gapped mine to 0.054 per the Helm manual. The 3.2L is no cake walk for changing plugs (plan a full day for your first time). You'll need the Helm manual instructions before you start! It's nothing like the straight six in my '65 Mustang (15 minutes tops)! lol
The 3.2L runs like a champ with them.
Another interesting tidbit about Iridium. It comes from asteroids! Much of it is taken from the layer of soil dating to when the dinosaurs were killed off, which is how geologists figured it was from a big-ass collision. I guess that's no big deal since the gasoline we use comes from decomposed dinosaurs. |

krypton is a mixture of six isotopes. At Room Temperature is a Gas, the Element Classification is Non-metal.
Not a good idea to make spark plug's with.
anything else?

Yeah we had a meet in Davenport IA that I put together two weeks ago. Not as big of a turn out as last year but we had track time and stayed at a really nice hotel. It was a blast!
So what mods do you have on the H3? PICS PLEASE!! |

Finished installing these and oh boy is it a fun job. I have pics but don't exactly know what the best way is to post them here there are about 15 of them. Should I start a new thread?
In general, me and member kissdaring were working on our two CTS's for like 3 hours trying to install these. What we ended up doing is not even removing the bracket but unscrewing only one of the bolts on the bottom which holds that bracket close to the engine and then just pulling it out a bit after loosening the second one. It is an absolute nightmare trying to get in there especially after 5 Stella's in your system. I'll start a new thread and post the pics there after I figure out the hosting dilemma. |
