2009 Maintenance Recommendations

[bronsin]

You want the plugs the manufacturer recommends!

Period!

It's not ok to use another heat range...long term. Short term...not a problem.

Unfortunately I don't know what the manufacturer specs...

I would re gap and put the old ones back if the new ones are not as spec ed.

This was one of the plugs NGK had on their site for this vehicle. So I feel ok with it. Obviously the other NGK's were doing their job. I only use OEM for the cars I care about, this is just my daily get around vehicle, so I'm less concerned about it blowing up. :)

The new plugs are gapped in spec, the old were a hair out, like .45 vs the recommended .41-.44, IIRC.
