As above is it an upgrade or any advantages if its possible to fit a 3 port instead of the 2 port that is fitted to my car at the moment 

3 port gives the mapper better control over the boost targets, so yes it's a upgrade.

But it has to be mapped in /calibrated straight away for it to work ,so is best fitted just before mapping or by the mapper

Ok cheers for that the car is getting mapped at the end of January so I will get them to fit it then thanks 

I've definitely got 1 of those in my boxes of scooby scraps £30 delivered [emoji6]

Was it you I was supposed to be looking for a maf for ?

If so what colour label was it ?

Yes it was but I got one from east kent subaru's in the end and it worked a treat

All iv got to get is the ngk plugs for it to run perfect but I will have that from you next week if that's ok coz money is tight at the moment but are they easy to plumb in 

Yeah easy to install ,if you get a classic oe subaru one they just plug in ,run new vac lines and map .

Took attowe 5 mins tops and 2.5 mtr of new vac line
