Fits ALL Honda / Acura B-Series motors.

This pulley has the ability to absorb vibration, smoothing out your ride
while reducing premature bearing failure and preventing oil pump breakage.

The pulley has a slight under-drive and is lighter than stock, so expect
smoother, quicker acceleration and a gain in horsepower and torque. This
pulley has no effect on alternator charge or battery life, keeping a full
charge just like stock, and works with your stock belts.

*** NOTE *** If your stock pulley is old, has chips or cracks, or
has damaged rubber replace it before it is too late! A crack or chip can
cause your engine to run unbalanced and could come apart at high RPM's.

Available now for only $80.00 + S/H
