Radiator Cap
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 consider it to be best OEM replacement cap since the Genuine Honda cap was discontinued a few years ago. The part number is G1010121551FUT if you would like to find one locally... I make $3.00 after the transaction fee.
The following interchange part numbers are just a sample of applications this cap replaces... and there are likely tens of thousands of additional applications. I simply found it by asking for a replacement to the 1991 Honda CRX/ Acura Integra PN: 19045-PM3-003.
