Airbox?

Is it the same on all the E85,s?

I’d imagine there’s a few different ones to cater for the 4 cylinder, the M54 and N52 engines and Z4m and Alpina models

Think the intake itself would be pretty much the same although there's after market options available and some have even made new scoops toward the grill at the front.

Put your reg into https://www.carparts4less.co.uk/ and it'll tell you about what you need to get under the servicing parts.
