air flow
 

I have a 2003 (53) WRX STI Type UK, I have a fault logged with the air flow meter and have lost a lot of power due to this. I have the hard pipe induction kit with the filter in the wing, has anyone got any suggestions on where the best place to get one from is? I have been quoted £267 + VAT from Subaru :cry:, is there any aftermarket ones available that may be better for the job? Car has been remapped to 340bhp. :wonder:
