Triumph 500 Twin 2-1 Intake Manifold late t100 daytona

Brand new production after being unavailable for years, original Triumph part # 70-7578 or E7578, depending on your parts book.

This manifold allows the conversion of '68-on Triumph T100s to single-carb.  (Note:  If you head uses 1/4" fasteners at the intake side, this manifold will NOT work for you.)

Simpler tuning, easier throttle pull, near-same power output.  And the manifold can easily be opened up on the carb side if you wish to run a larger carb for hot-rod apps.  As cast for std 26mm choke.
