Ignition coil DELPHI or APR

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.

Did mine recently, with new APR coils and more performance oriented NGK plugs.

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.

I won't install anything but the Delphi coils.

Don’t get Bosch coils or plugs. Get Delphi coils, they’re the updated design. As for plugs go with NGK

I’ve used both. Didn’t notice any difference. Have Delphi’s right now. Both work great for light and mid tuned setups.

My tuned 17' R has had RS7 plugs and APR coils for awhile without issue, but I'm ready for a new set.

DO NOT BUY APR COIL PACKS they are fun but life of It them are terrible stay stock!

APR coils lasted almost a year (5/6000 miles) when I pushed it and let go of the pedal. CEL would flash and random cylinders misfire.

As stated APR coils are know to not be as good as OE/OEM. I have seen a lot of people with APR coils chasing misfires and the replace with OEM and it’s fixed. Even with new APR this has happened.
