S54 Performance Oil Cooler

Tap right for info.

A smart OE+ upgrade.

It is designed to fit within the original plastic sleeve to optimize air flow in and away from the cooler.

Uprated, anti-vibration core.

As oil capacity is not increased, this is focused on improved core efficiencies.

It's black, just like OEM.

The finish is powdercoated to last forever.

No leaks.

The Radtec cooler has machined fittings for OEM O-ring fitment.

Build Journal: mechanical program
You wanted revs? You'll need cooling.

The S54 power levels have made drastic jumps in the 2010s and it brought out some kinks.

Along with the S54-EVO high duration camshaft package, upgrading the oil cooling was an obvious while you're in there.

In this entry, I document my unboxing impressions and installation notes of this improved oil cooler.

Enjoy,
