K-Tuned Adjustable EP3 Idler Pulley Kit - K20 / K24 Black

The K-Tuned Adjustable EP3 Pulley kit is the newest addition to the ever growing parts line-up. This simple and very useful part has been in development for a little while now, and was designed to solve K-series accessory belt adjustment issues. Up until now, people that chose to use the OEM Honda Civic EP3 Idler pulley have encountered problems with over-tightened or loose accessory belts. This is because the original factory EP3 idler is fixed and not adjustable.

The K-Tuned EP3 Pulley kit allows the user to correct the length of the accessory belt by manual adjustment, to keep tension in the perfect service window. This is especially useful as the belt stretches over time. K24 / K20 engine combos will appreciate the adjust-ability of this part even more because of the parts mixing that occurs on these setups. For some swaps, like a K24 engine swap into a 06-09 Civic, people have even started using the smaller K20 crank pulleys in an attempt to correct the accessory belt length. The down side of switching the crank pulley is that accessories such as the water pump and alternator become over-driven by the smaller pulley. Unlike K-Tuned's very popular A/C & P/S Eliminator Pulley Kit that relocates the alternator, the K-Tuned EP3 pulley kit also allows the user to keep A/C installed if desired. However, as a default the kit is sold with the correct length belt to delete A/C.
