    Tune up 850

    I would go to IPD and buy a tune up kit. It comes with cap, rotor and plugs.
    IPD offers several differnt brand of plugs and they can advise you what might be best. I just checked online and they are currently having a sale on their tune up kits.

    15/40 Rotella is not a bad idea either.

    Reach IPD at http://www.ipdusa.com

    Good luck.
