sportsfan1026 Posted November 22, 2005 Share Posted November 22, 2005 I bought a set of OEM spark plug wires for my 97 2.5L. Do each of them go with a specific cylinder? Or do I just put them on wherever? My haynes says they are unique but i cant find any numbers. Thanks Quote Link to comment Share on other sites More sharing options...
Cougar Posted November 22, 2005 Share Posted November 22, 2005 Usually they number the wires but if you don't have any then justmatch the lengths as best as you can. The wires are the same except the length. Quote Link to comment Share on other sites More sharing options...
ShawnW Posted November 22, 2005 Share Posted November 22, 2005 The only one thats longer on the OEM is the #2 wire. #2 is on the drivers side front of the engine. This is because it goes around more stuff if I am picturing it right. Quote Link to comment Share on other sites More sharing options...
sportsfan1026 Posted November 22, 2005 Author Share Posted November 22, 2005 Thanks, I will Check Lengths If i had the wires installed incorectly would it cause "arcing" when looking at the running engine in the dark? I checked that tonight and noticed arcing in several places along the wire's. Could I have gotten bad OEM wires from the dealer? What about the plugs I am using? No one had the NGK plugs (and I was in a hurry) so i bought the most expensive ones NAPA had which ended up being Bosch. The more i read this board I am begining to belive that my new plugs could be the problem. Thanks for all of your help Quote Link to comment Share on other sites More sharing options...
Cougar Posted November 26, 2005 Share Posted November 26, 2005 I'm sure the wires were ok when you bought them. It sounds like you are not making good connection to the plugs and that is causing the arcing. Make sure the ends are seated on the plugs well and check the coil ground connection also. Bosch plugs aren't the best for these cars it seems. I would order some NGK's from a place online if you can't find them locally. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted November 26, 2005 Share Posted November 26, 2005 go with NGK's if you can. newer soob wires can be a pain to seat properly. be POSITIVE they are seated. i pull them off and reinstall if i'm not positive i hear the "click" of it engaging with the spark plug terminal. good job noticing the arcing, that is not good and should be fixed ASAP. it won't do your wires any good and will eventually (if it hasn't already) compromise the insulation of the wires. i would bet magnecor wires would not arc, www.magnecor.com. awesome product. thing is...you might fix the issue by seating the wires or getting new plugs...but it still could arc if the wires have been compromised somewhere from the arcing.
