    Spark Plugs

    Hey, I've read a post on here about upgrading the ignition system on the sr20de by using a crane lx-91 coil with new leads ( thinking of TopGun leads ). Im currently running NGK BKR6E spark plugs gapped to 1.1mm which isn't bad but because I'm upgrading the ignition with more spark power I am thinking of gapping to 1.2mm which you cannot do on non 11 plugs so here are my choices. BKR5E-11, BKR6E-11 and BKR7E-11. I would like your thoughts on which plug will be best with a 1.2mm gap to avoid pinging. I know its a bit more of a test and trial sort of thing but maybe someone has done it. Cheers.

    unless you got some serious mods (like 12-1+ pistons), your current plug is fine.
    quality is remembered long after price is forgotten

    Those sparks will do fine. Make sure you replace the dizzy cap and rotor every 20,000 klicks.

    However, I have only ever used these: NGK Iridium IX plugs. Part # BKR5EIX-11, with the Crane/Top Gun combo.

    Make sure you start with a new dizzy cap and rotor.

    Like these:

    and a Crane/TopGun combo, and I guarantee, you will notice a positive improvement in performance.

    Cheers . . .

    Re my choice of plugs, I recall a discussion with Cozzm0, on why I used '5' instead of '6'.

    Went looking for it. Couldn't find. If think it was about my SR20 being a high-port.
