What do you guys think about the bosch plugs (copper) going into a b18a1 with nitrous? I know I should get the zex plugs or the ngk ones but I need plugs to run a 75 shot tomorrow at the track with detonation. I got 2 heat ranges colder than what bosch recomended for oe application. I have the ignition retarded 4 degrees with 93 octane too and the nitrous will be a wet shot. Do you think I will be safe with this combo? Also, what model number ngk's should I be ordering in for this setup?

 

honda = NGK
bmw,vw, porsche = BOSCH

75 shot - 1 heat range colder. Timing is safe where you set it.

i would not recommend bosch spark plugs on hondas, now they do make a kick ass dishwasher though! ngk all the way!

 

Well believe it or not but with the 4 degree retard and about a 65-70 shot I used NGK iridium plugs with oem heat range and it never detonated. I am pretty shocked because I always thought that iridium plugs ran a little on the hotter side than copper. The bosch ones were for a temporary fix but I guess I don't need them lol. Thank god cause this will save me some money on new plugs and new wires since I was afraid my NGK wires would break when I pulled the old plugs. Where do you guys get your NGK plugs from because all the auto parts stores up here are like ummm whats a heat range...so I need to go else where to get proper help!

 

I got a set of ZEX plugs...no need for them...come get em if ya want em...
