These plugs are OE off 3.0L Accord just turned topic miles. Replaced with NGK, also OM listed OE replacement. On RA Denso and NGK close to same price, but lowest cost shipping ~$8 for USPS ship. Denso significantly more at Amazon and Advance (~$3.50 each more). The latter where I ended up purchasing online, store pick up using 25% discount, ~$49 all in including tax. Lowest price of known reliable sources I could find. I saw where ebay has 6 for $22 and change. "IF" they are real, great price. Using RA, Amazon, AAP et al as comparison, seems too good to be true.
I checked the gap post use thinking might have opened up some. These factory gapped ~.043 all still right at that spec. Other than that nothing remarkable or surprising here. They did require some effort to get out.
A pic of a couple tools I found particularly useful doing the sparks. On the right, Pittsburg flexible ratchet that I purchased many years ago at HF, ~$10-12. Socket quick release and 72 teeth, made in Taiwan. Haven't used it very often but especially useful this time for the back fire wall plugs. On left, 390 Lumen Braun Magnetic Slim Bar Led Light, paid ~$20 at HF about a year and half ago. Again very useful for back plug visibility. Like it so much, got an extended parking lot sale coupon online email, again for $20, I may buy another this weekend.
