A high quality unit made by Japanese OE Supplier to Honda, Futaba. .9 BAR (13 psi) vented cap fits all TracTuff fabricated products using the small import style radiator cap bung. I honestly consider it to be best OEM replacement cap since the Genuine Honda cap was discontinued a few years ago.
The following interchange part numbers are just a sample of those this cap replaces; there are likely tens of thousands of applications that use this style cap. I found it by asking for a replacement to the 1991 Honda CRX/ Acura Integra PN: 19045-PM3-003.
