So my stock spark plugs (RE7A and RE9B) in my Renesis are worn (pitted insulator) after about 100 hours (including initial tuning/debugging).

AutoLite 2592 and NGK BR10EIX have been recommended as replacement plugs (if rotor housings have been machined or ground so socket will fit over them).

My question is: when using these alternative plugs, do you re-gap them from the 0.6 and 0.8mm gaps they come with?

Additional question: can I use the RX-7 stock plugs (NGK BUR9EQP/BUR7EQP) in the Renesis?

Hoping that perhaps dwalker has the answers.
