Do you have any plans on boosting your car? If so, install both the oil cooler and trans cooler.

Sad to say I wont... :/

Return the trans cooler and purchase a 25row oil cooler.

This is what is says on Z1 motorsport lol

19 Row (13" x 1 1/4" x 5 1/3") -- Recommended for most light street applications or applications in colder climates where less cooling is required.

25 Row (13" x 1 1/4" x 7 1/2") -- Recommended for more intense applications where occasional track use will be seen, also for more moderate climates.

34 Row (13" x 1 1/4" x 10 1/4") -- Recommended for forced induction applications, serious track use, or in high temperature climates where more cooling is required. Our most popular core, even though it is our largest standard offer core it still fits great even with Stillen Gen 3 intakes.


wouldn't 19 row be enough? Theres no tracks around where I live haha

Oversize the oil cooler. You can always make a block off plate if it's too cold. You can't add capacity if it's getting too hot.

the Z definitely needs an oil cooler. A few minutes of spirited driving will cause high oil temps. This should have been addressed from the factory but big surprise...its not a necessity so it won't be addressed.

This was the first mod I did on my Z, get one!
