    free power??

    If your like me, and are on a VERY tight buget but still have the need for speed, iam sure you'd love some free HP. i still got a front end to fix
    And since my throttle idea was a bust, i've been thinking about other free, or VERY cheap mods to get more power. Any ideas?

    Cheapest mods that actually give you some power are:
    1. Free-flowing Cold-Air Intake
    2. Free-flowing exhaust
    3. Performance chip/PCM re-flash
    4. Complete tune-up

    Platinum is old news guys. It lasts awhile but isn't a very good conductor. Iridium is the latest "hot-ticket". It'll outlast AND out-perform platinum by far. The only manufacturer I know that makes them is Denso. Check it out here:

    Denso Iridium seems to be the trend, but I have a friend who mines hardrock, and he says platinum is HARDER than Iridium. For a car application, I'll take Bosche.

    The point is NOT how HARD it is. The point is that it will last as long as the platinum in this application AND out-perform it in the ignition system because it's a better conductor than platinum.

    Actually he thought that platinum would be a better conductor, I don't just buy a product because of the advertisements for it, I buy it from my personal experience, but yea, I would try the Denso's, but I will wait until they are proven a little more in history.

    I know this is reviving an old thread, but....

    On the Platinum vs Iridium vs std plugs debate, some comments.

    1. I have run a few sets of Bosch Platinums. I have had reliability problems with the platinum wire "dissappearing" from the insulator. No way to know if it fell out and got munched, or burned up. (91 Bonneville 3800, 1 wicked iginition system from the factory....)

    2. Champions, suck. I have used 2 sets in my lifetime, and both had 1 plug out 8 fail. Flat out no conductivity anymore. Dead plug. Forget em.

    3. Autolite and AC Delco are the only plugs used in serious turbocharger applications. Why? Durability. They can stand up to boost and survive. Problems with them? None. Typically last 50K miles on std plugs.

    What I like about the BPlats and Iridiums, fine wire concept. It has a small area, so when the high voltage builds up, there is a much higher potential for spark under harsh conditions. So under heavy load and low rpm, the potential for missfires is less. Thereby more power and lower emissions.

    Personally, I stay with the AC Delco or Autolites, as reliability is excellent. The best being the Autolight double platinums. My 1996 Suburban with 191K miles just got the FACTORY spark plugs removed. Best I can tell, they were rough, but alive. Autolite went in to replace. Runs better, smoother, and mileage is up a little.

    So, that is my humble opinion.

    Iritidiums if they can survive would be a good plug..... Bosch Plus 2's have a lot of potential too. I like side gapping my plugs in my 80 T/A.....

    i think that i found a site on the ac-delco webpage that said that they are either coming out with or already have iridium plugs for most applications.found it http://www.acdelco.com/html/pi_plugs_irid_main.htm

    How about gutting the interior and removing the bumpers?

    I'll look at the iridiums when I change the plugs/wires on my 92 Deville. It will need them soon. Thanks for the advice!
