How long will the Herko BO39HE Igniton coils last ?
Rating Herko B039HE ignition coils for Silverado 2500
Can't give a 100% rating right now only had them installed a month and so far see no problems .
The Coils are very easy to replace and old ACDelco ones where 12 years old and the flat metal plates on the left side where separating. looked at ACdelco and they are very Pricey per coil and Delphi .Found the Herko Coils very reasonable for price and look just like the ACDelco coils . As for how long they last and are of the same quality as a ACDelco have no idea . Mine where in the 12 year range so replaced them all . Shipping was quick . a lot of the Brand name auto parts are way over priced and a lot of the after market parts are just as good as the OEM parts . Time will tell .
