BMW Inline 6 Firing Order
After many years of having BMW I had lost my taste for the style. The first BMW I had was a 323 Alpina which I drove the $hit out of. Was a great little car, and the engine was a joy to drive. Later on I had moved up to the 750iL and last one I had was the 850ci. Both of those cars is what feel like for me was the peak of my affection for BMW's. Enough of that, you came for firing orders. I had found few places that had a good supply of BMW parts in the past and always nice to toss a plug for Pelican Parts they have great selection and prices.
BWM Series - E3 E12 E24 E23 E28 E30 E31 E32 E34 E38 (more???)
Some additional model info, but the smaller and larger inline 6's all follow this pattern. This includes M20, M30 and other models of BMW engines. On later models the distributor is replaced with coil on a plug or similar systems, but the firing order should be the same.

Everyone has their favorite engines, my would be the M20 in the Inline 6 series. Simple and durable it seems as I beat one up and it never missed a beat. I still miss the 323 Alpina I had.
