MY GTO has a Mushroom Induction Kit which I thought was an HKS. I purchased some new filters for it and was away to fit them when I discovered they had holes in the middle of them when mine doesn’t rendering them useless and a waste of money!!!
Mine has no HKS button that you unscrew - they are held on with clips embossed with HKS Sports funnily enough but can’t find the filters.
I am glad I did it as the old filter disintegrated when I took them off.
Anyone know where to get replacement ones??
