I went with Denso Iridium TT's instead of the usual NGK iridium that Honda recommends in the Odyssey. It's been 70K miles since, no issues. I haven't visually inspected them for a while but I did around 40K of use and they looked fine. My VCM is muzzled so the engine is easier on plugs now. As always avoid Ebay and Amazon for spark plugs because of the higher chance of fakes.
