    IR = 3x as much
    They last 2x as long. Not worth the $$ to me.

    NGK TR55

    yes, they are pregapped -but you should still check them. 2 of my 8 were off a considerable amount. Its so easy to check them and if you don't your car might run like total shit.

    Start around .99 cent and go up. Most are under $5. I use feeler gauges.
