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.
