I'm also curious if these coils are any better than the eldors.......or are they just eldors with lipstick on? Not much info out on them as far as actual performance goes.....

Still running strong. No misfires or anything with 600+ to the rear wheels.

Updated chart on the original post (and below) comparing all 3 of the different OEM options as requested. Bosch/Delphi are essentially the same (what was shown in the original chart). New chart adds the Eldor's which offer a bit of a bump compared to the previous OEM options but still not up to the same output levels as the Dinan coils.

I suppose these are not suitable for N53 my oem number is not listed on the website 12137559842
Very interested in these, price is also reasonable, though importing them in EU probably would be slightly expensive. I don't expect my Delphi's to last very long, had already replaced 2 of them within 15k km. One failed due to mosfet failure and one just suddenly died on a startup. So was thinking to go back to Bosch if the rest are going to fail soon. Maybe they won't, recently did an update on dme, don't know if that has any effect on coils. |

Am I reading that chart right? As RPM's go up, DWELL between pulses goes down. So the higher you rev the motor, the more all three of those coils start to produce the same spark output....right? What am I missing? |

Ignition coils are quite a problem for N53's. Bosche's didn't really directly fail on me, but they slowly crapped out causing rare misfires and bugging/stuttering on low rpm acceleration. Delphi's as of experience can just suddenly die at anytime, even quite early. There aren't many options.. Eldors weren't really easy to get hands on here and not sure of compatibility. According to Bimmerprofs and to my understanding - the problem in short is - high voltage spike's can kill the ignition coils. There is a solution called snubbers, but it's a bit involving. |

You're missing ever having looked at the dwell table. It does not decrease with rpm.

So, if that's the case....looking at the graph, as dwell goes down (in MS), the power output of all the coils they are comparing gets closer to being equal. Or am I looking at that graph wrong? If I'm wrong....please explain that graph to me....

That's odd.....I've pushed 27psi boost on my turbos and never had any misfire issues with the OEM delphi coils and NGK plugs gapped at .022".

Agreed but there are a lot of variables. For example a lot of people can get away with a .022 gap but others might need a .018, or some stock LPFPs can run e50 fuel while others need an upgrade on e30. These cars are finicky and all have a personality of their own lol

Thought I would chime in on this thread since I have a rather strange n54.
I'm required to run a plug gap of .8-.9mm on my index 10 motor, the injectors don't leak but have a poor spray angle during idle which results in groggy running, at least that's what I've figured out. Under boost conditions the motors beautifully smooth. I've been running the dinans on the stock setup (stg 1+ at 17 psi for 10k absolutely flawless miles, they drive the 1 step cooler plugs at a current 0.8mm gap with very minimal correction. I do believe largely in the slight power jump, they cleaned the timing up nicely over my Bosch coils. If anyone thinks it's market jargon don't, their a good quality coil at a very reasonable price. |
