This is a genuine INA OEM (Original Equipment Manufacturer) part for the Audi S3 8V
As fitted from factory by VAG, these are a very common weak point on the EA888 engine causing coolant loss and overheating.
These generally need replacing every 50,000 miles or so, however we have seen some cars with around 20-30,000 miles failing.

Included in kit:
Water pump with thermostat housing – INA
Belt kit – INA
Coolant Coupler – VAG cross reference no. 06L 121 131 / 06L121131

As these are OEM parts you can rest assured you are getting the same quality as genuine, without the price tag.
