got hold of a mk4 golf airbox and had a go of fitting the jetex cone filter inside the standard airbox. this is whati got from it which i'm happy about.
in the bottom of the box i drilled lots of 54mm holes. to help get more air in but still keeping it oem looking
second mod the day, mist washer jets, after reading a thread about using TT needing glueing i didn't bother, got a pair of washer jets from a MK3 seat ibizia for free which is a bonus
here they are fitted, no glue needed just used a flat file to remove a bit of plastic as they are a bit bigger then the standard one.
mod cost £0
