I have just checked the mileage on the lridium spark plugs I installed a week ago. I have a power commander pc-111 , big shots
barons BAK and I found I get about 4-5 more miles per gallon and better performance with these plugs. I put on 110.60 miles and took only 2.5 gallons I never got better than 37mpg. I do play with the the throttle to 110 plus did( I say that). the plugs are great try them.

thanks denis, after reading the origanal thread i went and ordered some NGK Iridium spark plugs, should have them next week. What did you gap them at? and what's their color looking like? The extra milage is a bonus, the extra power snap is what i'm looking forward to.

I have been running NKG plugs forever,in everything I own. I have tried others but never been satisfied. Take a look at the Land Cruiser forum (mailing list actually). You'll find 1500+ members who swear by NGK. Prove to me there's a better plug and I'll buy it. Until then, I'll stick with what I know works and works well!! Not tryin to dump on you Roughneck. I just feel pretty strongly about the NGKs.

yeah oldman no problem just good to here others opinions all I know is most of the mechanics and pit crew guys I've known have had nothing but bad to say about them and the only one's i've had experience with went bad really quick but they were the bottom line version. this is actually the first time I've heard good things about them so I might just look at them if y'all can tell me which of there product lines are good. thanks

Will my nads glow in the dark and keep time with my iridescent plug wires also[:0] Remember the glow in the dark watch hands and hour indicator found in (analog) wristwatches from the late 60s?
I just sent the following message to motorsportsbest.com.
"Iridium is a known radioactive carcinogen. What is the percent concentration of Iridium in the conductor, the mass of the conductor and which isotope are you folks using? What is the proper disposal method for these plugs?
Thanks for your assistance in answering my questions."
Hey; at least the risks, if any, will be known! I'll wear my Nomex coveralls for the follow ups[/emoticons/emotion-2.gif]
I will try to find a contact at NGK and Denso to deliever the same questions to.

Just go with the one listed in the manual. It calls for an NGK or a Denso.

just got done with my first ride with the ngk iridium plugs, and gosh darn, they do make a difference. It took it out the dairy run, lots of twisties, and short straight aways, with the stock plugs i typicaly got up to 110mph before i had to brake for the corners, now i get up to 125mph before i have to hit the binders. Also seems to warm up faster and have stonger pickup when you shift. All in all I am pleasantly surprised with just a plug change. Is worth the $40 that they cost me. I haven't had such a bigger grin since i installed wilskie's custom map for my settup. Also was glad i have a BAK, made changing the plugs out a breeze. will let ya know if i get better gas mileage. btw, i bought the NGK DPR7EIX-9 stock# 7803

My plugs just came in tonight and I have yet to put them in. I figure I have a couple of days since it's been so rainy here lately.

I actually found the plugs for 6.95 each on line.

I look foward to seeing if there is a change!

after reading about the advantages of iridium plugs they are definetly at the top of my list. they are good for cold starts, burn carbon as it developes & last 100,000mi or better.
