Are coil packs really only designed to last 50K?

 

The COP coils on our Acura were still going strong at 180K miles/12 years.

The coils on our Fit are still OK after 80K miles/5 years.

 

Mine are still good at 130k.

 

add me to the list!

just changed the 4 coils with 150$ ebay ones and they are working perfectly

car runs sooo smooth!

 

So who's the manufacturer? ebay's not enough info. ZAnd $150 perr?

 

it was for all 4

2007 2008 New Set of 4 Ignition Coil on Plug Coils Pack for Honda Fit 1 5L UF581 | eBay

they seems really cheap tho..

 

Checking the seller, ACauto, reveals a very high customer satisfaction (more than 2000 submitted at 99%), but there's no indication if the coil packs are that good, just overall shipments.
However, I would not be surprised to find the manufacturer may be an OEM who is willing to sell at a price not much greater than OEM prices.
So until a couple of Fit owners go out on a limb and tries them we'll be as wary as this poster. But the next owner who comes here with ignition problems we may take a chance ...

My cohort got an answer on the low cost coil packs. They didn't identify the manufacturer but said it was an OEM supplier. Certainly $124 plus shipping certainly is a good possibility.

 

The SAE testing performance is good for 50,000 miles or equivalent. When Honda says 110,000 miles thats the tyopicallife from those tests. Like everything, there is a spread in the actual lidfe of devices. For coil packs the -3 sigma, or the earliestg coils start to show failues is about 40,000 miles but owners should expect to get a hundred thosand miles.
Now that the prices of coil packs are coming down to earth, like $125 for 4, the maintemnce of copil packs is beginning to get real with cusomers.

 

^^Thanks, mahout.

 

2 months later my cheap ass ebay coils pack are still running fine!

 

Canada, eh?


(j/k)

 

hummm yes, what's your point?

 

^^No point. Just a poor attempt at a joke. Sorry.

 

:P

yeah from quebec canada, where coils pack for fit are 130$ each and where they take 50% of our pay check!

Can we switch

 

[QUOTE=SilverBullet;1157135]Yes but they developed the ecu. There is no reason the coils cant last and if you use the right oil and fuel it will last at least to 100,000 miles. My dad has used Kendall oil and premium fuel in his car since day one and has no coil failures. The car is 16 years old and has over 100,000 miles with no coil problems and the engine is still like new.

Does ethanol content matter? It seems that I get better mileage with non-ethanol, but do you know if the coil packs last longer with ethanol or non-ethanol? Non-ethanol tends to come in premium where I live.

 

[QUOTE=ErinM;1167193]I think it does. The engineers use a high octane and pure fuel when they set up the motor and ecu. There is a difference in premium gas I know only 1 brand around here that does not use ethanol in their premium and that is what I use. Knock is what damages the coils and ethanol blends are not consistent but if you use premium with ethanol it resists knock better than regular.

 

[QUOTE=SilverBullet;1167289]Maybe you could TRY and explain how knock damages plugs when the Fit has a "knock sensor" that prevents knock (in most cases). Then try and tell us just how knock damages coil packs. It's not like they know what is going on in the combustion chamber and current flow is not magically effected by conditions other than resistance.

 

I've never put premium in my Fit and haven't had coilpack issues in >100k miles.

Save your money, use the cheapest gas, premium isn't required. The Fit's engine isn't going to knock on regular unleaded, if it did, the manufacturer would recommend higher octane.

 

I never use premium in my Fit and I have had no coil pack problems. I'm at 82+k mi.

 

A knock sensor retards the timing only after knock was detected and will retard the timing to all cylinders to prevent knock. There is oil jets that spray the pistons to cool it off and it sprays in the middle of the piston above the spark plug but there is a oil ring that forms over time which can cause a hot spot that cause pre ignition. Coils fail due to contamination and usually caused from knock that pressure escapes from the plug causing the coil to overheat and misfire. There is a lot of the variables that all play into knock and not just fuel. Cycle to cycle variables, oil blow by, to name a few.
