spark plugs with stock heads and E85

[dynoman]

I had the ar133's in for one day and noticed my car hiccup at least once during a WOT blast . It happened every time I went WOT , then I read about others having the same problem with non-resistor plugs . I switched to NGK BR6FS (4323) non-projected tip , resistor plug , gapped @ .028" http://www.autozone.com/external-engine/spark-plug/ngk-standard-copper-spark-plug/505335_0_0/
Problem went away and I have run boost @ 28.5 psi . Plugs are only $2.49 each plus you can get them at any auto parts store .

As always we appreciate the various opinions!! That being said is there a safe plug that will not blow out with reasonable gaps on E-85 and common sense? Resistor vs non? Gaps that work w/ stock ign.? So many ways to go...................

I ended up with the NGK UR5's. I also bought a set of the UR6's so far the 5's are working fine gaped at .030". Thanks for all the feedback.
