[jase555]

hi all smee again,
would anyone have or know where i can buy an air intake sensor from. mainsteelers say it comes with the air box and mfa and want £75 + vat. 
if anyone could let me know the part number and what other cars its found on it would be a massive help too.
my car is a 1995 (M) mk3 gti 8v, engine code 'ady'

thanks guys.

update
part number is 028906081 and is available seperately @ £24 + vat. a little easier on the pocket and i think i will get it new. 

thanks anyways.
