Hi all, Recently bought an ITG induction kit off of the bay for my S3, unfortunately it hasn't come with the foam filter. Anyone able to advise what size of foam filter it needs and what I.D. should be? I've measured the pipework and it's around 89mm I.D. Can measure properly later on when I get a chance. From reading the ITG website the collar is 1.5mm so O.D. is +3mm. Cheers guys.
