This part is a customer-paid option, and in order to avoid further delays and inconvenience to our customers, these vehicles were supplied with the standard Oil Filler Cap in place of the Jewel version. This condition has no impact on vehicle performance, safety, or engine operation. However, the part may not meet the expected visual or branding standards defined for final vehicle presentation, and may therefore fall short of customer delivery expectations.
