Reviews of Bosch ignition coil

One of my Bosch coils went bad within 13 months. Probably would have happened with Delphi for all my luck. Nevertheless, I returned all six to FCPEuro for lifetime replacement warranty.

I use the Bosch, and Ive been happy with them so far.

Bosch.

Never had issues with the Red Bosch ones I got from Shopdap.com But plugs, I preferred the NGK Ruthenium HX over the Laser Platinum, and Iridium-IX

9-3’s eat coils; it’s a forever problem on my 9-3 that it seems like every 30k miles I’m spending $200 on new coil packs. It’s essentially routine maintenance. I ordered Bosch OEM coil packs off RockAuto and just now realized they have a warranty. I submitted a warranty claim and they sent me out brand new units. Wish I would have known this because it would have saved me lots of money.

I have used the 027 coil in a beetle with with points and the coil was getting hot. It was solved by using the 039 coil (Bosch grey).

This is a new Bosch coil (but also happened with old coil), wires, cap, rotor, and plugs as mentioned above.

Had thrown some 2 years ago and still running clean as ever

Just replaced my coils. AVOID Bosch. Literal trash that does not even work.

I have changed the ignition coils, spark plugs, MAP sensor, fuel filter, and ran fuel cleaner in the tank twice. The only time it seemed better was for a couple of months after I changed ignition coils (Bosch).
