Recommendation on forced installed non-compatible sparkplugs

[nascar]

Not sure if they can do the job but you can try asking:

thanks sir!!

well, another solution is to just use that same type of delco plugs if wala namang issue sa takbo.

by the way sir, I forgot to tell that only 2 non-compatible sparkplugs were force installed. The other 2 sparkplugs were compatible and of the same size. So,what would you suggest in that kind of situation sir? Thanks.
