In case the engine is operating at variable speed always select your spark plugs in reference with the highest speed range.

(*) In case the variation of the LHV of the utilized biogas exeeds 10 per cent it is recommended to used 76.64.292 (S7664761) spark plugs.

(**) In case of very contaminated gas it is recommended to use 76.64.292 (S 76.64.761) spark plugs.
