2010 Chevy Cobalt 2.2 spark plugs
I was about to hit 100,000 miles so I thought that I
would replace the air filter and spark plugs. I
accidentally installed ACDelco 41-108 and I
should've installed 41-103. Is this a big issue? The
plugs were the same size and everything fit okay
but is there anything I should worry about and
should I change them? Any advice would be great,
thanks!
