rynicolson Posted August 12, 2023 Share Posted August 12, 2023 Can anyone advise what the spark plugs recommended for a 1.6 Supersport K series are? Have found a set of Bosch Super 4 FR78 509's whilst de-cluttering and can't remember which car they were for! Thanks in advance. Link to comment Share on other sites More sharing options...

revilla Posted August 12, 2023 Share Posted August 12, 2023 It does make a difference whether it's EU2 (probably - with a distributor) or EU3 (less likely with SuperSport - with coil packs on top of the head). The BCPR7ES (with a "R") include resistors needed in the EU3 wasted spark setup. The EU2 has longer, resistive leads and so a non-resistive BCP7ES would be more appropriate.
