EP3 Idler Pulley Kit

Thanks to the KPower Intake Manifold throttle body flange position, RWD K swappers are now able to retain the OEM K series belt auto tensioner and OEM belt routing. 

In order to do this, you'll need to install the EP3 (02-05 Civic Si) idler pulley above the auto tensioner. 

As of July 2021, this is the standard belt routing we are supporting for all of our K swap packages using a K24A2 engine.

Note that this part is only compatible with USDM K24 water pump housings and tensioners, and not the JDM K24A housings. 

This kit includes the pulley, pulley bracket, bearing cover, and special center bolt.
