honda parts dealer in saddar rwp azhar shaheed market. however the exact # of plugs if i remember correctly is NGK SILZKR7C11S. if you get these in NGK packing they cost less anyway. i probably got a bit older stock in honda packing but i even verified their resistance and multiple close and comperative inspections. found them orignal. using them since a year now.
however i am not sure about recent price, but i think i got the 4k price coz the dealer wanted to clear his stock (the feeling i got, coz he had lots and lots of plugs stocked at that time).
AL HAMD U LILLAH no issues and good experience.
