Already searched no flaming.. Will they work in my b18c1? This is what smucks auto supply recommended.. But on the ngk website they are for non-vtec..

 

Heat range of 5 is a little hot shoulden't it be like a 6 for a stock or light modded engine?

 

thats is for the non-VTEC engine

plus i dont think the VTEC engine uses the ZFR series plugs.....i belive they use the BK plugs.......

 

for NGK use: BKR6E-N-11 or Iridium BKR6EIX-11, i run both, prefer to run copper for many reasons.
for Denso use : K20PR-L11
champion: RC8YCC4 (this is the plug I run...$10 for all four its not a bad deal)

the following are for non-vtec, and should not be used on the b16a/b18c motors
ZFR5F-11 or in Iridium ZFR5FIX-11

here what the plug means:

 

hey thanx eg6ajk, thats some helpful info
