I've been following your thread and it's been a pleasure to read.
Good job on the headlights. I personally prefer to rebuild stock Hella headlight units myself, I've done it 2 times so far with great success.
You just get EVO XR or Hella G4 projectors that bolt on and are million times better than the old stock projectors. Throw in some new DJ Auto headlight lenses and you get fantastic headlights. One of my favorite mods you can do on an E39.
Yeah I was aware of the possibility of swapping out the lights but I was looking more for a plug & play option this time around. Be careful what you wish for.
What about the angel eyes, what did you do for those during your previous swaps? The previous owner put in a new LED for them which gave it more of a blue tint, but the current ones are significantly brighter and not as blue, so really like how they came out.
ahh just saw that the DINAN intake came with the car... disregard my comment then, but feel free to add notes related to it if you can. Did the kit relocate the temp sensor on the passenger side? Any thoughts you have on intake sound would be great. thanks!
Yeah the IAT sensor was relocated with new wiring into the DME. The Dinan is definitely more involved than a simple intake swap with having to add additional brackets, swapping out the fog light surrounds, and all the sheet metal to prevent water from hitting the filters. I'm assuming you read about how I took all that out...
Anyway, as for sound, I'd be lying if I told you I could tell a difference between my car and the only stock M5 I drove. Honestly, with the mufflers removed, the exhaust noise is more audible than anything else. Perhaps with the stock exhaust system, you'd hear an increase in intake noise. The power gains are negligible though it does help the engine bay look nicer.
