vs
Ignition coil DELPHI or MSD
Delphi. BMW started with Bosch and after misfire issues they switched to Delphi (I think in 2011?). Go with Delphi, my old e82 with an n52 had tons of misfires at 40k with Bosch coils and the Delphi’s had no issues.
Pros: no misfire issues
Cons: misfires with Bosch
Vehicle:
BMW
Mileage: 40000 km
I had issues with misfires until I replaced the coils with genuine oem. Before that I had all new Delphi 10571 which were not the same and ultimately fixed my misfire issues.
Pros: fixed misfire issues
Cons: Delphi coils not the same
Part number: 10571
I won't install anything but the Delphi coils.
Pros: reliable Delphi coils
I’ve always had good luck with MSD coils. I’ve had them on MULTIPLE vehicles.
Pros: good reliability, good performance
Don’t get Bosch coils or plugs. Get Delphi coils, they’re the updated design. As for plugs go with NGK
Pros: updated design
I’ve used both. Didn’t notice any difference. Have Delphi’s right now. Both work great for light and mid tuned setups.
Pros: work great, no difference
Vehicle:
BMW
I purchased the MSD coil upgrade kit, swapped out the coil pack, new spark plugs / wires, fresh oil / filter. Fired her up and she purred like a kitten.
Pros: purred like a kitten
Vehicle:
Volkswagen Corrado
You can also spring for the MSD coil, about twice as much but the boots are attached better I think, where the OEM part might have the boots rip off or the springs get caught up.
Pros: boots attached better
Cons: twice as much
So I replaced the coils with MSD packs, and tossed in fresh plugs, even though the old ones were less than 10k miles in. This seemed to fix the issue for a while, but it ended up coming back.
Pros: seemed to fix issue
Cons: issue ended up coming back
Vehicle:
Ford
Mileage: 10000 km
I have used the MSD ones before but they will fail much faster.
Cons: fail much faster
Vehicle:
Ford Mustang
