Audi Under Supercharger Service Kit - 3.0T B8 - GPS Aluminum Thermostat Assembly

Complete Under Supercharger Service Kit for Audi 3.0T Gen 1 B8/B8.5 - Essential Supercharger-Off Maintenance

Everything you need for supercharger-off service on your Audi B8/B8.5 S4, S5, A6, or Q7. This comprehensive kit includes GPS billet aluminum thermostat assembly, aluminum heater pipe, Graf metal water pump, OEM PCV valve, and all critical gaskets and seals that should be replaced when accessing the valley of your 3.0T TFSI engine.

Why This Kit is Essential:

When removing your supercharger for carbon cleaning, thermostat replacement, coolant leaks, or performance upgrades, these are the parts you should replace while you have access. The B8 platform commonly develops coolant leaks from the thermostat housing and heater pipe, while intake manifold gaskets and PCV components deteriorate over time. This kit bundles everything in one package, preventing the need for a second teardown.

Common reasons for supercharger removal:

• Coolant leaks in the engine valley (thermostat, heater pipe)
• Intake valve carbon cleaning
• PCV system failure causing oil consumption
• Rough idle from worn intake manifold gaskets
• Ported blower installation or pulley upgrades

Kit Benefits:

• Upgrade to billet aluminum components where OEM uses plastic
• Premium OEM and OEM-equivalent parts only
• Everything needed for one complete supercharger-off service
• No second teardown for parts you should have replaced the first time
• Ideal for DIYers doing carbon cleaning, ported blower swaps, or preventive maintenance
