Swiftune H4/HS4 Trumpets
Swiftune's dyno tested and developed carburettor Trumpets to suit either H4 or HS4 SUs.
2 1/2" long, each trumpet is exquisitely CNC machined from billet alloy with a super smooth radius to aid air flow into the carburettor. These not only perform perfectly, but they look stunning too! Over 100g lighter than cast versions.
