JDC Titanium Coolant Reservoir Hardware Replacement Kit

The JDC titanium coolant reservoir kit is made from Ti6Al-4V (Grade 5) titanium. This kit will work on the stock reservoir and most aftermarket reservoirs that use the same mounting points. This kit will allow you to replace your ugly stock hardware with beautiful titanium that will outlast your car itself! Titanium is around 45% lighter, way stronger, and will not corrode like your stock steel bolts.
