Have a HKS filter kit there for Legacy. Lying up a while so would defo recommend replacing the filter (€20). Never actually fitted as I had another mushroom filter that i put on original inlet. Paid €200 odd from JDM distro. Will sell for €150 to members. Makes your car go sututuutu
In the spirit of @Pedro555 kind gesture with the exhaust earlier, this will now be free to whoever wants it. Sure its only sitting there gathering dust
