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)
