Recommendation on forced installed non-compatible sparkplugs

[mangdencio]

thanks sir!!



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.

nascar, leave the remaining spark plugs in situ as they are. strive to install the original spark plugs on the damaged holes once they're machined.
