Beschreibung

High quality steel breather valve for use as stock or high performance replacement. Note: S&S breather valves come with elongated breather holes to increase the duration of the vacuum; allowing more oil to be drawn from the cylinder heads.

Do not intermix steel and plastic parts. Note: A .030" oversize breather is available to save worn or damaged crankcases as 518662. A JIMS breather hole reamer (MCS 978343) will ream the damaged hole to +.030" so a +.030" breather can be used.
