I'll be installing a set of New plugs in my 2000 Sahara. Should I get Champion 7034 or Autolite App985's. And should I replace the wires also? I have 124-k on her. I believe the original owner MAY have had them changed, but am not sure.(need to look thru the papers) The wires look to be ok, But I'd like to get some opinons before I get everything tomm. Thanks.
