Are Delphi coils better than Bosch?
I would go with the Delphi option. Used on F80 which has a lot more power from the factory than N54 engines. Btw the oem ones from Bosch also come in a BMW stamped variant. Those are tested to a higher standard and hold up better.
What is the resistance of a Bosch coil?
The Bosch Black Coil (made in North America) has 3.4 Ω primary resistance. Ideal for use with 4- and 6-cylinder Hot Spark ignition kits.
How many ohms should a ignition coil have?
A typical value would read 0.4 – 2 ohms.
Are Bosch ignition coils good for BMW?
What OEM options do I have? If you’re familiar, you would’ve heard about Bosch, Delphi and coils by now. They are the OEMs for BMW ignition coils but, they are not all the same. Bosch was the main manufacturer for BMW’s ignition coils for quite a long time, before Delphi and Eldor came along.
Do high performance ignition coils make a difference?
A high performance ignition coil helps engine performance four important ways. First, the higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal at the start of combustion. The result is a real-world engine torque increase.
Is Delphi the same as Bosch?
Bosch is the OEM injector. Delphi is a high quality OEM alternative. Problems with either one? The price difference is about $100.
What should the ohms be on a coil?
You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, a little less is ok but no more.
What Ohm ignition coil should I use?
The 3.0-ohm coil should be used on PerTronix Ignitors installed on four- and six-cylinder engines while 1.5-ohm coils should be used for eight-cylinder applications. These coils can be used on virtually any inductive (non-capacitive discharge) ignition system.

Where do I find the 4465 and 4470 spark plugs?
There is a thin plastic tab below the triangular section for the plug that makes them fit specific to those vehicles. I wouldn’t cut or remove that like another reviewer did.

What kind of ignition coil does a 2006 BMW 325i use?
For 2006 Bimmers (325, 330, 525, 530, Z4), Amazon might show that the part fits but notice there is fine print underneath saying “From 04/2006”. Look inside your front driver side door for the BMW sticker to find your manufacture date. Based on 325xi, cars built through 03/2006 will use 0221504465 Bosch ignition coil.
