Hello..Im new here. Have a 13 auto lx . Im 66 and this honda is my very 1st gas car.. car has 74000 right now, and although no problems. I wanted to replace the coils with ngk and ngk plugs. the orig coils are Honda-denso. should I stay with the denso coils instead of ngk.? I like preventative doing things. Is this overkill at this milage ? oh..and the drive belt !!..Although I love my non turbo Benz diesels, I enjoy this civic !
