Best spark plugs?

[Jon March]

Any recommendations? I saw a 6 year old thread that mentioned
Bosch Platinum Plus 4032 -

any more recent wisdom??

These aren't high performance engines .. .. that being said I have used Champion RL87YC and (currently installed) Bosch WR7BC

Thanks - Looks like the new number for the Bosch WR7BC is "Bosch 7997" - Thanks all!

The NGK BPR6HS, else NGK Iridium IX BPR6HIX, is equivalent to the Bosch WR7BP

Many people prefer the NGK's but it is probably like arguing over the best religion or the best motor oil!
