Ignition coil DELPHI or OEM Audi

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.

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.

R8 coil packs definitely work better IF you’re tuned.

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.

Delphi will be all you need. Delphi are fine even on ST setups running 700+whp. There’s really no need for others.

Stepdad recommended replacing ignition coils, so I purchased a 4 pack of Delphi GN 10369 from amazon. Sure enough, we just replaced the coils, and boom, it ran good as new (to me).

NGK plugs and Delphi coils. Do not get Bosch

I had troubles with Delphi units. Replaced all 6, then replaced them again with a wty set. Still had issues.
