NGK BKR6E on Stock KA24E

[PHeller]

Like the topic says. Hear lots of good things about these but I don't know if I should them on a stock KAE, or they are more for turbo cars. Any insight?

those are one less colder plug than stock.Just use the bkr5e for stock.You are correct the fi setup need to run a colder plug.
