Can someone tell me what size this fitting is?

circled in red. I need to find out the metric size/pitch so I can place an order with summit today for an adapter to -10an line (oil cooler)

Thanks!

18mm x 1.5

seeing that was answered, what size is that thread for the oil send for the turbo

14mm x 1.5?

actually I contacted Mazdatrix, and they told me the fitting I originally circled was 16mm unit, so I purchased the 16mm to 10an adapter and washer from them.

I don't recall what the upper turbo oil feed line is, but 14x1.5 or 14x1.25 sounds correct. I'll confirm it this weekend
