Three checks before you buy.

01

Match the original valve

Compare 06A145710N, 06A145710P or Bosch 0 280 142 114 with the existing part. Match the valve layout and recirculation system.

02

Check all connections

Confirm the 25mm hose connections, vacuum hose connection and clearance in the engine bay.

03

Check engine and spring setup

Use the application guide below. Audi TT Mk1 1.8T 210/225 bhp is included; follow the TTRP guide for red, yellow and silver spring setup.

For turbo petrol engines with a matching vacuum-operated 25mm recirculating valve. Match the original valve reference, both hose connections, vacuum connection and installation space. Vehicle name alone does not confirm fitment. See the application guide or send us your existing valve reference before ordering. Ask us to confirm the exact application if you are unsure.
