Re: Need to know year of 75 HP Chrysler
I cant say cause I am not a spark plug guy. Specs seem pretty similar though This is a the L20V
Racing Plug, 14mm Thread, 12.7mm (1/2") Reach, 13/16" (20.6mm) Hex Size, Gasket Seat, Non-Resistor, Surface Gap
This is the 2852
14mm Thread, 12.7mm (1/2") Reach, 13/16" (20.6mm) Hex Size, Gasket Seat, Non-Resistor, Copper Core, Surface Gap
Here is the L20 V
Champion surface gap V plugs have a .050"annular configuration with no ground electrode. Engineered for extremely cold application, the firing tip is nearly impervious to pre-ignition, however, fouling deposits can be problematic. These plugs have extremely limited use in racing and require a special high energy ignition system and a very rapid rise time(CD). Constructed with a nickel shell for faster heat dissipation and copper core or double copper (when noted) for further heat removal, all racing plugs are non resistor (unless specially noted).
And here is the 2852
Autolite spark plugs are engineered for every type of internal combustion engine. Copper core aids in cooling and improves resistance to fouling. Surface gap plugs have no ground electrode attached to the steel shell to project toward the center electrode. Rather the outside steel shell itself acts as the ground, removing all chance of plug induced pre-ignition. For use with capacitor discharged ignition systems only(CDI).
