I purchased these valve covers/gaskets from Amazon for $109.99 in August of 2018, with the intention of replacing the valve covers/gaskets on my 2002 Maxima GLE with a bad oil leak. I ended up trading in the Maxima for a 2015 Infiniti Q50S in September, before taking on the job. I was out of the 30 day return window on Amazon, so I got stuck with them.

Asking $100 OBO PayPal, UPS shipping included.
