Review on 17670-S5A-A32 Engine Dancer Gas Cap Fuel Cap Fuel Filler Cap ⛽ - Honda S2000, Insight, Accord 4dr, Civic (non Si), and ACURA NSX (2001-2005) by Bryan Gibbons

Bought this replacement gas cap about 2 months ago, overall it's a great cap, it fits my 2001 Honda Civic. however, it doesn't serve its purpose at all, as it has a hole in the white plastic vent that allows petrol fumes to constantly escape, it's most likely a casting defect. I could smell them when I got out of the car after the ride. I'm sure most don't have this defect, but be careful.
