Re: spark plugs (darkred91)

It depends on your needs. If you have a mostly stock car, or even slightly modified, good old ACDelcos or Champions will do just fine. IMHO, let the flaming begin :rolleyes: , all those special plugs with two, three, and four electrodes aren't worth the dough. I've not seen back to back dyno runs comparing each, but my gut feeling is that you're not going to see a difference, no matter what their marketing departments tell you.

The Bosch Platinums, if you do a ton of driving, can offer a benefit, because they'll last longer. This is great if you're like me and don't like struggling with the plugs on a regular basis (30K or so). Put the Platinums in, and you're good for another 100K.

:cheers:

I like the Denso Iridiums. But, they are a bit expensive.

Re: spark plugs (MaddMaxx)

I've always wondered.....
What is the life expenctancy of the Iridium plugs. I can't seem to justify changing plugs that cost that much every 30k miles.

Just wondering.... :confused:
