Thank you all for your time and advice .
Just as a point of interest , my Boxster was 1st registered in October 1999 , but is a 2000 model i.e. 2.7 litre 168 Kw tiptronic . It has E-gas and that is the reason why the MAF is a 99660612400 Bosch No. 0280218009 ( in Europe )
I believe that to be able to use a 12500 MAF , I would have to upgrade the DME at the workshop and this costs approx £1000. So , I will stick to the 12400 lolol .
Again , thanks All for your support and advice
