Lotus Esprit / Excel - camshaft sprocket / auxiliary pulley.  This is a direct replacement for Lotus part: A912E2019F; the post 1985 HTD type pulley with "green dot" 104 degree timing.  These later HTD type pulleys are more reliable than the the earlier "square tooth" pulleys and are therefore a popular upgrade for the earlier engines fitted with the trapezoidal (square tooth) pulleys. 

These pulleys are CNC machined from billet aluminium and hard anodised like the OEM pulleys for proper long term wear resistance.  

Please note any customs charges/import duties are the responsibility of the purchaser.
