When I was at the parts house today, I asked for plugs same as the last set. He looked it up useing my phone # on the computer and said,"No problem". When I get home and get my Venture torn down, he has given me plugs with a 7 instead of an 8. (DPR7EA 9)They look the same ,so whats the diff, hotter?,colder? or what. Would it hurt to use them or should I take them back. 50 miles one way.
Thanks
Richard
