P/Ns from the CSL:
11317835041
11317835043
Do recall the CSL is based on the Euro E46 M3 with a different exhaust/cat setup. N.A. E46Ms have 330hp, Euro has 343hp, CSL is 360hp. On top of the cams and exhaust, there's obviously the airbox. When you put all that together, the +27-30hp really doesn't seem like much.

There are definite differences in the Euro spec Z4m and the US spec version of the Z4m. Not just pipe/cat wise either, but the emissions too. Easy to spot them by just opening the hood. Actually, I am pulling that out of my arse, not sure if those emmisions differences are GCC spec, as we have Jack shit emissions control/pollution gear here on all cars.  |
