Just an update on this issue. I decided to ditch the K&N pod in replacement for an Apexi Power Intake.

I have also ordered a brand new air flow meter from ebay (which all the numbers match up to my old one):

SUBARU WRX 22680AA310 1974002090 AIR FLOW METER NEW | eBay

So yesterday it arrived and I installed them both. Tried started my car, and every time it would kick over for a second and then die.

So I then installed my old air flow meter and it started fine and did not die.

Took it for a drive and most of the sputtering has gone away but the car still does not feel 100%.

Am i correct in assuming that the air flow meter I recieved from ebay is faulty. And i should contact and recieve a replacement item?

Any help is much appreciated, Cheers
