Beautiful car. I assume that gauge in the center vent is the AEM wideband 02 sensor. Forgive my ignorance, but what's the purpose? Do M50 swaps run lean or something?
91 325i. M50 swap. Well sorted.

Yep thats the wideband gauge. The next step was to turbo my car and this was one of the peices i could install at the time. I actually had a manifold, a turbo, injectors and a chip. The turbo ended up being a POS and i ran into other problems forcing the sale of the other parts. Oh well. I can find another vent and keep the gauge if you wanted.
I have no reason to beleive the thing runs lean at all. If it ran lean in the 5series it came out of it might but im pretty sure it didnt.
Thanks for the compliments!-ChrisComment
