HIF4 Piston & Suction Chamber Assembly — Dustproof | LZX 1967

Genuine SU Piston & Suction Chamber Assembly for HIF4 carburettors — Part Number: LZX 1967.

A complete piston and suction chamber assembly — the core of the SU variable choke carburettor. When the original suction chamber or piston is worn, cracked, or damaged, engine performance deteriorates significantly. This genuine replacement restores original carburettor function.

Genuine SU manufacture — made in the UK to original specification.
