    My Predy 79 came with a Torch E4RC spark plug. Some people claim a good plug will make a huge difference in performance. I could use a shorter plug with better performance. Any tips or suggestions?

    Here's the list of plugs compatible with the Torch E4RC:

    NGK (3322 / BR4HS)
    Bosch (WR10AC)
    Brisk (NR19)
    Daihatsu (99906850P9002)
    Denso (IWF16 / W14FR-L / W14FR-U)
    Honda (98076-54757)
    Motorcraft (AER6)
