Works as intended
Do not cheap out and get an off brand. I went through three different Oriely off brands over a 14 month period and all of then kept the check engine light on. So I purchased another $900 or so of emissions and other parts trying to chase the check engine light for almost 1.5 years until I finally bought the OEM gas cap that fixed my check engine light. Not worth the gray hairs and scratching your head to try to save ten bucks, get the original cap here.
