Hi, could you please tell me the spark plug gap on this car? I have seen in the Honda manual 39-43, but every where I read I see 44. Did Honda change the gap and I just have an older book? Any help is appreciated. Thanks for your time. Neil

I looked up both of the very slightly different 2.4L engines for that car and can only find a suggested gap of 0.39-0.43. Nothing about a 0.44 gap anywhere.

39-43 is what the specs I find say. But 44 is probably one of the preset gaps the plug companies machines runs at. There should be a gap listed on the sticker under the hood telling you the spec they want as well. That would be the one I would use.
