TracTuff M14 x 1.5 Adapter

Description

The Honda K Series has a very limited number of crankcase breather ports. The most commonly used port is on the valve cover; though it works, it is the furthest point from the source of pressure AND the baffle makes it a pretty restricted port! The other port is the PCV (Positive Crankcase Ventilation) found on the water pump housing and for some odd reason, the internet has guided consumers to plug it rather than use it. Strange being its one of only two possible connection and it’s also the ONLY vent in the actual crankcase (where the pressure originates) which makes it a great point to try and reduce pressure that could be hurting performance.

One end of the adapter has a 14mm x 1.5 thread and the other a -6 male flare. The ID of the 14mm end of the fitting dictates how much flow will pass and being you cant go any larger, it doesn’t make sense to use an AN size any larger than -6.
