Quantity: 2 plugs
MADE IN THE USA

Fits:
All* 1965, 1966, 1967 and some 1968 and one or two 1969 Rochester Quadrajets with brass cup plugs.
* Note: Service replacement carburetors may require the later/smaller plug #1743, even though the carburetor number indicates a 1965-67 model year. the actual production year may be different.

Q1742

Q: How does the O-ring plug work with today's ethanol enhanced fuels?
A: We have used this plug in our own vehicles for 6+ years and have not had any issues at all. Not sure if the o-ring is made from ethanol resistant material, but it has not caused any problems in this type of static application.

Q: Can the plugs fall out during use?
A: No, cone shaped nipple on back of plug takes up clearance to throttle body ensuring the plugs can not fall out.
