Z1's Lightweight VQ35DE Alternator Pulley was designed to complement our VQ35DE Crank Pulley, replacing your car's stock steel pulley with one machined from 6061 billet aluminum. By reducing the weight of the accessory drive system, you're restoring horsepower lost by the engine as it spins the heavier pulleys. The diameter of the pulley matches stock, retaining the use of factory-size belts and preventing issues from over or under-driving accessories.

• 65% lighter than stock
• Machined from billet 6061 aluminum
• Factory size retains the use of original belts
• Direct replacement for OEM pulley PN 23150-AG010

Fits:

• 2003-2006 Infiniti G35 Sedan
