Our N54 catch can and expansion tank combo allows you to replace your factory, prone to cracking, plastic expansion tank. This tank also has a catch can integrated into it and allows you to vent your valve cover to the atmosphere to help with oil consumption and also keep your intake valves clean!
This is our updated version with all barbed fitting for clean and extra easy install. This kit comes complete with the coolant side hoses, and hoses needed for the catch can side. All you need is valve cover fittings.
