K-Series K20/K24 USDM Water Pump Passage Housing

Description

Genuine OEM Honda K20/K24 USDM Water pump passage housing.
If you purchased a JDM K24A2, you may have noticed that the alternator is attached differently then the USDM K-series engines.

You may also have found it to be very difficult to find a replacement alternator that fits the JDM housing.
Another issue is that the standard idler kit does not fit the JDM housing, but we have a solution to that. Another issue that this creates is the clearance for the intake manifolds.
All in all, it will make your life easier by switching to a USDM water pump housing, even if you want to run the Skunk2 manifolds this will make it easier.
