I've been doing some research on late Bosch type MAFs and hopefully this information will be useful to others. I have a 2005 2.7TDi and the Nissan part number on the MAF sensor housing is 22680-7F406. The housing contains another smaller tube inside the housing that MAF sensor dangles into. A replacment MAF sensor from Nissan is £323.92 +VAT. It is possible to buy genuine Bosch replacement versions for £190 inc VAT.
This sensor differs from the earlier sensor which has part no 22680-7F400. I tried a sensor of this type and it gave amazing low down torque but as soon as the car warmed up it lost all power and I could only get home by disconnecting the MAF sensor and switching the ignition off then starting again.
The 22680-7F406 sensor is also used in the 3.0 Terrano. The Nissan part number refers to the complete unit so the housing and the sensor itself. My research indicated that the corresponding Bosch number was 0281002596 and that this used the sensor insert with Bosch part number F00C 2G2 061.
This sensor insert is also used in other manufacturers MAF sensors. In particular it is used in the 'Vectra C' with Vauxhall part number 93173727 (or Scania part no 24437503) although the housing is wrong. With the correct 5 pointed security bit you can remove the sensor to examine and swap it. A new genuine Vectra sensor with Bosch number 0281 002 479 costs £130 inc VAT.
To confirm this I bought a secondhand Vectra MAF housing with sensor and it does indeed contain a sensor insert with part no. F00C 2G2 061. I swapped the insert with my tired old original and now I have loads more torque at low rpm, there's not much difference at high rpm.
So to summarise, if your Nissan MAF sensor has part no 22680-7F406 then a cheaper alternative is to buy Vauxhall part 93173727 and swap just the insert into the Nissan housing.
