I put 2500 miles a year on my car so these should last me a good 4 years and I couldn't justify the price difference in that after 4 years I'd change plugs no matter what kind I used.
got damn...only 2500??? that's two thousand five hundred miles rite??? kaka...i go no less then 2500 a month...

The rest of the time I just Zaino it and it sits in my garage under a car cover. I'm an old man and the stick is no fun in traffic anymore.

I dont need no bling blingin' spark plugs.

debating on which one to get..some say the irdiums are just a waste of money
That's what I've heard. I'm running plain TR6s
Check the gaps before installing. They come pregapped, but it's just piece of mind to be sure they're all gapped correctly BEFORE installing. Hate to install them and always wonder if they were right.

i will never ever ever run platnuims again. i never put them in my ls1 and i never will. my old mazda mx6 had copper vpowers and they ran perfect and colered perfect i gave it a tune up with platniums and the car imediatly was slower less reponsive and i was told they are horrible and known for detonating motors especailly f/i motors. i then pulled em out with only 200 miles on them and they were all black and nasty like somthin wasnt right. put vpowers back in everything went back to normal and the next time i checked the plugs in about 500 miles perfect coloring again. a buddy also has seem those plugs come out glowing unlike anythinghe has ever seen before. they hold heat and do cause preignition and stuff , id stay away, the iridiums seem to be good i have them in my car currently i also ran the tr55's i havent noticed any diffrence.
