Hey Wolfox! Did you ever...

get those Iridium plugs? I remember a post a while back about some plugs you we going to try out. Did you and how did it work out??

Watch out WOlfox he is very tired possibly.yeh i wanna know too lol.

I haven't changed them out yet. The only reason why is because the current set of plugs in the truck aren't worn enough to warrant a change. As soon as they do wear out I will swap and let you guys know. My truck does not see a ton of mileage, except on weekends - I can and do walk to the office in the mornings. :)

Nice, I drive 42 miles each way. It's not too bad being all Xpressway but it still sucks when you're beat!

What sucks more is having to walk because you spent your gas money on Iridiums! I looked high and low,and found a set of them that would work for the GM 4.3 from Denso. A local store has them in droves since so many Hondas and such are carrying these plugs from the factory. $13 a piece! *sticker shock* <<faint>> But I figure I would wear out 4 sets of tires before I replaced those plugs! The trick is finding them in the proper heat range for the 4.3 smallblock 6. Ideally you want a plug that heats up to operating range within seconds of engine start - but not so hot that you suffer from pre-ignition. You can hit the Denso website and use their application guide to pick what you need.

What are the benifits of Iridium Plugs??

I bought NGK Irridium plugs for my T/A , but haven't installed yet either . I paid $ 7.00 each for these . Rob

Iridium is an EXTREMELY hard, noble metal. It resists wear from heat, and more improtantly, the tips do not vaporize as fast from the arc crossing them. Essentially, it is a plug that runs MUCH longer, within tollerances than even platinum tipped plugs or nickel plated steel and copper of conventional plugs. Those are the benefits in a nutshell. Secondary benefits come from the shape of the electrode tip and in Denso's case, a U-channel electrode. THis allows for a sustained, hotter and more even spark kernel that is not so prone to "blowing out". This increases idle quality and overall efficiency of the engine slightly. Another design advantage is that the electrode tip is "sharpened" to a fine pont. It's tip is only like 1.2-1.3mm compared to a standard platinum tip or conventional plug that averages 2.2mm or so. ELectricity loves to gather and arc from sharp corners or small surfaces. The plug will fire with less than half the energy required to arc across the gap of a standard plug. Ignition systems that utilize an Ion sense ignition system (Like me 4 Cylinder Rodeo did) can adjust the spark intensity to match engine speed and load better. On standard systems, it will simply fire with more intensity without upgrading to an aftermarket coil pack. I found out much and amazing info by Googling up general info on Iridium based plugs. Denso and NGK alo released papers on the effects of iridium based plugs in PDF format. They're simply good mojo that works well in almost any application they are put into.

Very detailed info, thanx haha almost makes me wanna go out and ge a set for my blazer
