Amplifier — a genuine BMW part, number 65 24 6 907 121. The number stamped on the part is 65246907121; BMW's catalog files it under the short number 6907121. You will find it on our Instruments & Electronics shelf, under Other Audio, Navigation, Electronic Systems parts. It supersedes the older number 8368208, so a part carrying that number is the same part.
It fits the E46 sedan and coupe (320i, 323i, 325i, 328i, 330i and M3, 1999–2006), with the M52, M54 or S54 engines — and the European-market versions.
BMW draws it on the Single Parts F Rear Window Antenna (65_0480) diagram. It weighs about 103 g (0.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
