How long do they last, how many miles?

Thank you for inquiry. According to manufacturer, unfortunately,there is no single answer to this question. As spark plugs grow older, they lose their sharp edges as material from the center and ground electrodes is slowly eroded away. As the gap between these two points grows, the voltage required to bridge the gap increases proportionately. Even the best ignition systems will be strained to supply enough voltage to completely burn the fuel. It is at this point, when fuel is being left unburned, that the time has come to change spark plugs. Replacing worn out spark plugs with new ones (with sharp new edges) effectively restores the ignition system's efficiency. Misfires are reduced, power is restored, economy of operation is enhanced and emissions are reduced. The best guide is the manufacturer's recommendation for your vehicle, as this particular service varies from brand to brand and model to model. In the absence of this information or in conjunction with it, you can rely on the advice of a mechanic who is familiar with your type of vehicle. In the best of all worlds, this would be a mechanic who is also familiar with the vehicle you own. If you find a good mechanic, whether dealer or independent, stick with him. The better he knows your personal vehicle, the better he will be able to diagnose and service it. The end result is very much like a doctor-patient relationship and, in the long run, you will have a healthier vehicle. Don't hesitate to contact us if we may further assist you.

Somewhere around eight or nine minutes sustained flight. It seems like all of them can fail for no reason and I have had one of this type fail. But they seem to last longer than any of the replacements.

I have used these for about 4 years. They have been lasting close to 1.5 years. I have had no problems.

For me , they last about 4 months. I use them in a home repair business but must add that I do not use them everyday.

Celeste, I currently own 6 of them and they are close to being 6 years old. However, I really don't anticipate they will last forever, I have read several reviews of units lasting as long as 15 years. If mine give out today, it's a cheap investment, and they work...

I've gone for like 5 miles and the batteries never quit so I don't know how long the batteries last because they're still working

I've had mine about a year, use them every day for at least 3 or 4 hours. Still perfect.

They're supposed to last 90 minutes, however, I tested mine and they ran for almost 3 hours, better than advertised.

They last a long time. I can't tell you how long I had the first one but I know it was at least five or more years.

I suppose It depends on the amount of usage. But I have had mine since November 13. Used moderately but not heavily. A couple times a week for 30 min to 1 hour each time. I like them. If I could afford the $40 a piece ones I would get those over these any day. But for the money they do what I need them to so and so far no sign of wear.

I can't speak to the lasting; I sold my vehicle about a Year after putting them in. In that time it lasted fine. They were an easy fix and quite inexpensive; if you get 2+ Years out of it you would be well ahead of the game. After I put them in my vehicle handled better and I actually gained a little bit of fuel economy.

They're good for about three years. They only last about a week so that's plenty of time.

Mine last between four and five days depending on how long you have them on.

I read somewhere that these are suppose to last for up to a year. Just make sure you keep them stored somewhere cool.
