High-pressure pump internals for the Audi RS3 8P and TTRS 8J 2.5 TFSI (CEPA). Factory piston is 10 mm; this kit is 11.5 mm, which is the usual 2.5 TFSI upgrade volume. Complete unit with upgraded spring and seal housing.
- Piston: 11.5 mm (OEM 10 mm)
- Fitment: RS3 8P, TTRS 8J 2.5 TFSI CEPA
- Typical use: Stage 2+ / big turbo / E85 once the low-pressure side can feed it
- File: must be written for the new pump volume. Fitting it on a stock map is a waste
