Would it be an outright dumb idea and is it even feasible to install the CSL airbox (and have the car run) on a bare stock non-HP DME? Reasoning: the rest of the parts needed for the install (save for a converted and flashed DME) just came in but I have a trip lined up this coming week (before which I'll send off the DME for the conversion since I won't be using it) and I'm jonesing to hear that sweet noise and get a little ahead so that when I come back, I just have to plug the now-converted DME in and enjoy. I think the reasonable middle-of-the-road option would be to enable the alpha N option on the ECUWorx tool, right?

Even with running Alpha N, you will be flowing much more air in the the engine with the CSL airbox over stock. My guess is that you will run lean without a proper tune.2005 BMW M3 ZCP Black/Black - HTE Tuning | Kassel CSL DME | 288/280 Schrick Cams+DLC Followers | Lang Head | Dinan TBs | Bosch 550cc | Radium Fuel System | Karbonious CSL Airbox+OE Snorkel | SS V1 Stepped+Catted Sec 1+Resonated Twin Pipe+Race | 3.91, 3 stage clutch | FCM 400/600 | Vorshlag Camber Plates, RSM | Rogue ASP | AKG FCABs, SFBs | TMS Front Sway, Camber Arms, Monoball RTABs, Pullies | Mason Race Strut + X-Brace | AS 30% SSK | SPAL | Redish Plates | Turbo Toys V2 Hub | WPC Rod Bearings

btw how in the world are the throttle body boots clamps on the airbox side supposed to be reused? Ive tried flattening the ear on them to get them to wrap to their original position with no luck. Are they ok to reuse with the next up position?2002 TiAg M3 Coupe (SMG to 6spd), 2003 Jet Black M5

You need the 01-04 boots, or these:

technically they're one-time use clamps but I've been reusing them. I bend them out so they're "square" rather than pinched in at the bottom. I used dikes/diagonal cutters and carefully pinched them to tighten them. Now I bought the proper tool to pinch them .Last edited by zzyzx85; 02-09-2023, 10:29 AM."your BMW has how many miles!?"

Have reused them before, used the wrong tool, worked fine.

Having run the airbox on Alpha N back in the day, before MAP running it was an option, I wouldn't do it (and, in fact, back then went back to the stock airbox for a couple of years, until the MAP based setup became a thing). The car may run right in specific instances, but never overall.
