ECP do geniune bosch MAF's for 80 quid exchange, VAG/bosch is the same thing and is about 180 quid new.

I'm running the hitatchi bolt down coilpacks that ECP stock and haven't had one fail in 18 months, bosch VAG part lasted about 4 before dying. The hitatchi seem to be coil pack of choice though.

I've put 50k on my 1.8t since its been remapped, its @ 120k now. Apart from 1 MAF, 1 MAP and a set of original coil's dying @ 80k, its been perfect. The problems are usually down to the maintanece of the whole car than fault components.
