Ignition Wire Replacement
My 1991 Civic's OEM ignition wires are now five years and
66k miles old. The 1991 owner's manual replacement interval is four years/60k miles. Tegger says he does his on his 1991 Integra at five years, period, though he lives in a northern climate in Canada (and I like what he says about ignition components). I live "out west" where in summer it's kinda hot, and for nine months of the year it's pretty darn warm. I would think the higher heat where I live would argue for more frequent replacement than Tegger's schedule. The following has been on my mind: I check the wires' resistances once a year. The resistances haven't moved since purchase. I wash the wires off with water about twice a year. They do get pretty dusty. My 1991 Honda continues to get great fuel mileage, continuing to average about 40 mpg around town even in winter. Last summer on a 1000 mile highway trip, the car got 45 mpg. Is there anything undetectable, so to speak, that could be going on with my Honda's ignition wires that would warrant replacing them a.s.a.p.? Or could I go another year without replacing them? I also remember reading here that ignition wires made today (or thereabouts) last a lot longer than those made in 1991. Comments? |

As long as they are OEM wires I'd think you can go almost forever on them. Wiping them down with some silicone might not be a bad idea just to keep them supple and clean, but other than that, do (newer) Honda wires ever go 'bad' ? ? 'Curly' |

Maybe not. Other than from unusual physical trauma, OEM ignition wires fail primarily due to insulation breakdown. This is impossible to measure with a multimeter. If your area experiences very high summer heat, I suppose that may contribute to insulation breakdown. > > Is there anything undetectable, so to speak, that could be > going on with my Honda's ignition wires that would warrant > replacing them a.s.a.p.?

I'd be willing to guess the insulating polymers are probably more robust than those available 16 years ago. If you get a good strong spark at the plugs, and you never have signs of weaker starting when the weather is very wet and the car is cold, your wires are almost certainly just fine. I've personally found that wires tend to start leaking current once they get past seven years of age. You can tell leakage easily: Engine running, wires soaking wet, grab a wire with your hand. No shock? It's fine. Get a tickle? It's failing. Get a jolt? It's gone. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

You can tell leakage easily: Engine > running, wires soaking wet, grab a wire with your hand. No shock? It's > fine. Get a tickle? It's failing. Get a jolt? It's gone. Just to add... If you look under hood when the engine is cold and it's dark, can you see any sparks coming off the surface of the wires with the engine just started? They will be pretty faint and difficult to see but will indicate that the insulation is failing. It's less painful than John's method above but not as definitive. Otherwise I'd continue to use them. -- Graham W http://www.gcw.org.uk/ PGM-FI page updated, Graphics Tutorial WIMBORNE http://www.wessex-astro.org.uk/ Wessex Astro Society's Website Dorset UK Info, Meeting Dates, Sites & Maps Change 'news' to 'sewn' in my Reply address to avoid my spam filter. |

Ignition Wire Replacement
Thanks for sharing your experiences, Curly, JBeam, JT (=
Grumpy AC), AZ Nomad, Eric, Tegger, and JYanik. I am going to hold off. I will continue to also use the checks Tegger describes, and on which some others of you touch, regarding looking for leakage when the engine is running. Eric, I read the background of the Honda/Toyota garage whose site you linked and studied its maintenance matrix. Interesting indeed. I am not wild abou the oil change interval (but let's leave that out of this thread, controversial as this subject always is!). Everything else looks pretty consistent with my own feelings and/or conventional wisdom here. I have bookmarked the site. I am going to hold off on replacing the wires for at least another year or until I see some symptoms, as you all suggest. At about $40 (online OEM sites) per set, and with the life of the car maybe not "five years more(!)" anyway, I think it pays to wait. I hear you, JT! As always, wonderful group, with great community service by all the regulars here in particular. |

My 1991 > if it works, don't fix it I just replaced the original ignition wires on my 12 yr old Chrysler Concord. They were OK, but I felt it was time. I also replaced the original PVC valve hoses; they had failed, it's several years past their lifetime. |
