    Ok, so I pulled my spark plugs (Denso iridium) today to look at them. They've been in for about 20-30k miles now. Im at 50k miles. Been hearing a lot about these E3 spark plugs. Anyways, when I removed my plugs I noticed that the porcelain looked really white and clean. I looked it up and found out the my engine is running lean. I haven't had any check engine lights nor error codes set off. Is it really too lean?? I have a K&N intake and most likely need to clean my MAF sensor (never done it). What do I clean it with?? I also have DTLT headers. Would I benefit from a URD MAF:

    or maybe the URD MAF Fuel/timing calibrator:
    http://www.urdusa.com/product_info.php?cPath=66_72&products_id=1260198051
    The reason I mention the second is because one of the fixes for a white (lean) plug tip is retarding the timing. Thanks for looking and helping.

    I don't know much about your particular problem, but I have heard that iridium plugs don't run great in 2nd gen 6 cylinders. I think Chris 4x4 did a write up on this in the technical chat forum.

    Have you used the plugs?? Is that just personal opinion or do you have more info on them to share?? Thanks.

    I hope not. I can check where the headers bolt on. That would be the only place where there could be a leak at right?? I forgot to mention that I have a unichip and boreal exhaust and o2 sims for the back to sensors.

    I was thinking that somebody may have tried to reuse the seals when the headers were installed. On a first gen, those seals aren't reusable. Don't know for sure if it's the same on a second gen.

    I have the Nippon Denso Iridium plugs in my truck and from what i can tell my truck still runs in an amazing fashion. those plugs are not designed to be ran for 50k from what i have heard since they are high performance plugs. hopefully its an easy fix but i really doubt u would have had any problems anyway... but it is better to be safe than sorry
