Think its a B&M cooler with a pro kit.
Fair big, about 35 rows. Large lines and the thermo unit means the oil only goes to the cooler if needed. Which makes it better for cold starts and street use. Always has 5% flow to cooler to keep pressure and oil moving.
Was keeping after parting out skyline for use on my next project but the 13b has a stock oil cooler and this ones a bit big for my 1200 ute.
Only bad point is I lightly spray painted one side silver to make it less noticable on the street. (Was mounted infront of FMIC).
Has spares to fit other car types but currently made to fit RB/CA/datsun/etc.
$200
in SA
