Yellow injectors
 

Hello all I've just brought a impreza uk2000 sep 99 I'm starting to look into getting more power out of her I was looking at bigger turbo, bigger inter cooler, remap ect ect I was looking at getting yellow injectors as I was guessing I had grey injectors in there already had a look today and I already have yellow ones on there the question I'm asking are these standard out the factory or has these been fitted as a upgrade? And my next question is if these are not standard does this mean the car has had a remap to make them work on the car? :hjtwofing

Hi there welcome yes yellows are standard on the later uk cars mines a 99 and has them

99-00 uk cars have yellow 440s fitted at oem.

Ok brilliant thanks for that
