88 85 hp Spark plug options

[Matthew A.]

Due to RFI issues affecting my sonar unit, I would like to use a suppressor type inductive spark plug. However, Champion nor NGK list a suppressor plug that is equivalent to the UL-18V or the BUHX. Does anyone know of anyother plug that can be safely used.

You may have to put a noise suppressing filter on the power line to the accessories effected.
Check Radio Shack.
