2013 equinox approved
Fits a 2013 Chevy equinox no problem. Came really quick and was a real life saver. Definitely a good part to get if youre like me and forgot to put the cap back on before you started driving 🤦

Great, affordable OEM replacement.
As the title states. I used this on a 5th generation (10-15) Chevy Camaro application. Works and is the same exact design as the original factory oil fill cap.

Perfect fit oem oil cap
Perfect fit. Replaced the correct "fit" one from certain auto part store. Leaked 1 quart every 3 months due to a bad seal. 10 out of 10 perfect fit.

Great price for a dealership item. Exactly the same new one as the old one for a whole lot less than what you would pay at the dealer. It does what its supposed to do!!! If this review was helpful please hit the "HELPFUL" button below. Thx
