Are there any risk running regular (copper) NGK plugs in a b-series vtec motor for daily driving/road racing?

 

none at all

they are actually a little better depending on who you talk to.

the reason for the stock plats is less maintenance (they last longer..hence the price)

just keep your gaps right and replace them a little more often.

personally, I love these Silverstone BERU plugs (check my site)

Replacing them is not a problem. I'm going to run 1-step colder if anything. How often should I change them.........10k miles?

15k is early but healthy

 

0.050 gap should be right, correct?

 

0.041

 

Standard electrode copper plugs won't fire as consistantly as a laser-tip electrode. If you road race especially I would stick with a laser-tip electrode plug.

 

I use the Champion (RC12MC4)cheap *** plugs, they only cost .99 each.

Work well and burn very clean.

 

Why does the helm's manual say 0.051 (for B18c1). Denso recommends 0.052 for 94-95 Del Sol B16a3 and 0.050 for 99-00 B16a2. NGK recommends 0.052 for all B16a's.

 

i run 0.041 but i have an msd and no problems ever come up. gap at what the helms says for you type of car.

 

I have always ran copper plugs
BKR7E-11 only resently have I switched to BKR7EVX-11 and they work great just a little more costly.

Today I started to look at Iridium plugs and NGK has some nice ones.

BKR6EIX-11 Stock # 3764 looks promising. It's a little over $7 a plug and has a nice small electrode to help flame propagation.

They are available here

BTW, I've always run .044 gaps in my B16 and B18c5.

 

Another thing, Denso catalog says to run 0.044 for B18c1/B18c5 and B16a (stated above). What happens if you run it slightly bigger or smaller?

 

Bigger (wider gap) from stock will make it harder for the spark to jump the gap, but will expose the spark more.

Smaller (narrower gap) will make it easier for the spark to jump the gap but will leave less of the spark exposed.

If your running higher compression, more dense a/f mixture, nitrous, or turbo/supercharger, you want a smaller gap so the spark can push through and light better (more fuel molecules in the way)

But we are getting too technical. For a stock or mildly modified ITR, stock gap works fine. If you want to bump it up a little it should be okay.

 

yep that sounds right

 

Aren't the copper plugs for the B-Series motors the same ones that are ran in the non-VTEC B-Series motors (i.e. Integra LS,RS,GS)???

 

That sounds right for me too.
If you prefer wider gap and colder, then try Brisk (# DOR14LGS)

Any comments on the bosch 4's for daily driving and high rpm driving?[QUOTE]
