M3_Power 636 Report post Posted April 23, 2019 (edited) Replacement O rings for the stock coolant hoses made of Viton 75 and Silicon 70 I saw kits being put together overseas and decided to do similar for those of us in NZ so I bulk purchased quite a lot of these to make it economical! $10 for all 3 on the left.
