I'm going to be replacing my 2007 Fit spark plugs (Denso Iridium Power IK20L # 5358) this weekend, trying to determine what that proper gap should be. Furthermore if they do need to be re-gapped, what's the best method and/or tool to do the job?

Thanks in advance.

 

Im new on here I didn't no if anyone could maybe tell me or sum thing to help me no what to fix on my 2007 Honda fit its misfireing on all cylindes but number two

 

I'm planning to get a set for next service. Let me know if it's any good.

 

I have a 2013 and right now plans for my next plugs are Denso 4702 IK20TT. They come pre gapped but I do not know if that is optimal but it would be easy to mess up those ends by trying to pry them. To make the gap smaller you may be able to just tap the electrode end on a hard surface.

 

I used the #6774 plugs for my 2007, who is right on their spark plug choice?

 

When I replaced plugs last year in my now-defunct GD3, I used these Densos, which I believe are ik22 / 3401:

gap at .041"-.045" is rather standard

I just use the gapping tool from any autoparts store. Don't pry against the electrode though cause it will usually break.

 

I have used Denso Iridium Long Life plugs and never touched the factory gap, and recently at 167K miles decided to use the Denso TT plugs and gapped them to .046. The care runs AWESOME!
