    Re: Maggie Leaking???

    I will probably end up running the TR6ix. The TR6ix, AC Delco 41-985 and its replacement 41-110 are all Iridium tip plugs but I cant find a heat range chart for AC Delco anywhere to get a plug 1 range colder than the 41-110. Most threads I have read recommend the NGK TR6 for the maggie motor.

    I believe, TR6 is roughly 1 heat range cooler than the 41-110s but not positive. I usually run TR6BREF plugs on our ls3 maggie motors (on ~9psi). If you want iridium tips, I can't remember the delco number, but have heard good things about the factory ls9 plugs.

    Gonna try the AC Delco plug # 41-104. I believe it is one heat range lower than the 41-110 plug. The 41-104 is the stock plug for the V2 and ZR1.

    Yup, that is the one. Should work well.
