Alright well i had some ngk r5671a-9 ngk 2 step colder plugs in my old b20 turbo setup and i am having trouble finding 2 step colder for the a20. So i was comparing my b series plugs to my a20 plugs and the distance they sit in the head is the same along with the threads. The only thing i see that is different is the a20 plug has a fatter porclein part of the plug then the b series one but i dont see why that would be a problem. So should it be fine if i run these instead?? Thanks!
i would say as long as the electrode isnt going to be hitting the piston, then yeah it is really worth a try. i had imagined the holes threads were the same, so they are? anyway, i dont think its going to cause any problems, just as long as the clearance is good inside the combustion chamber.
get BPR7ES NGKS

Just order the plug you need online. The dealers listed do stock them. If you want 2 steps colder for lxi, you need heat range 8.
you said the porcelain part is shorter? the spark will have too long of a distance to jump. the plug wont hit the piston, but you might have some problems with the spark reaching, if that makes any sense to you.

This is true. With forced induction you want a colder plug so it doesnt get tooooo hot and detonate. Stock honda plugs are run pretty hot even for NA so 2 steps colder is practically a must for boost.Quote:

Depends on which ones they are. For an A20 turbo, you'd want the BPR7EIX or colder. I can get them, if anyone is interested. $40 for a set, shipped anywhere in the US.
