Your oil is the lifeblood of your engine, and if it overheats then it starts to lose viscosity - then Bad Things happen. Keep your oil cool with this standalone oil cooler. Cooling your oil will also help keep your overall engine operating temperature down as well.

This is oil cooling done the Flyin' Miata way. All of the components are top-quality because a failure means the potential for rapid engine damage. The lines are braided stainless steel with AN-8 fittings on the end, sized specifically for this application. An oil thermostat is used to make sure the engine comes up to temperature quickly. The brackets are laser-cut stainless steel for strength and durability.

The cooler is mounted to the steering rack. It`s high enough to be protected from road damage but will pick up airflow coming through the nose or from under the car. You can add extra ducting if you want.

Bracket design may not be exactly as shown, it varies depending on the year of your Miata. Not compatible with old FM turbo kits that have a steel compressor outlet tube crossing in front of the engine.

This kit will work fine with our oil filter relocation kit, but they should NOT be plumbed together - install them according to their respective instructions, and don't change the hose routing, and it will work fine.

Easy installation and a great product!!!

It's ok, but could use some improvement

Bought last year to control oil temps in my supercharged Miata. Install was tight and left me wondering if it was too low. Well, the combination of Vmaxx coilovers and oil cooler was a time bomb waiting to happen. I run my shocks at there highest setting and still exploded my oil cooler on a canyon road 1k miles from home. Prior to smashing the heat exchanger, I was still seeing oil temps in the 240 range when sitting still. The kit could probably use a way to pull air as opposed to using the cars forward momentum to provide airflow.

Note from FM: While it's more susceptible here than in other locations, since the oil cooler is higher off the ground than the subframe, we would expect damage to the subframe as well with significant damage to the oil cooler. Unless the oil cooler protected the subframe. On oil temps, 240�F is completely reasonable - you really want your oil to get to at least 212�F each time you drive to boil off contaminants (and, ideally, trap them in a catch can). You should pay attention to oil temps around 280�F and don't let them exceed 300�F.
