NEW! TDR Engine Oil Cooler Kit for 90-93 Miata 1.6L

The TDR Engine Oil Cooler kit is a mirror setup of our Rotrex supercharger oil cooling system just mounted on the right side.  The cooler is mounted in the bumper/fender area using a stainless steel mount. The braided cloth cooling hoses are attached to a filter sandwich mount using AN flared fittings.  The sandwich mount has two 1/8” NPT openings for optional temperature sensors and/or pressure senders if desired. The custom cut ABS plastic panels are for closing off and directing airflow to the oil cooler.

Where is it mounted?

NOTE: This kit is not compatible with fog lights. You will have to remove them for additional clearance but the opening will provide increased airflow to the oil cooler.  If you have the stock radiator shroud, you will need to drill or cut a hole to move air toward the oil cooler.

How durable is this kit?

The oil cooler is a rugged design and potential damage from rocks and such are unlikely.  We have years of testing this location on street and track applications with no damages from debris.  We use these setups mainly for track use so winter use is usually not an issue.  If you are concerned with winter use, we recommend installing an inline oil thermostat. or selecting one of the built-in thermostat sandwich plates.  

What can I expect?

It is common to see around 25°F lower temperatures in the engine oil which in turn will lower the water temperatures as well.

For the NA6 Miata's we have added the TDR-O-SAND to be used as a spacer to allow clearance between the engine block and Oil Cooler Sandwich plate.

or You need to replace the oil filter stud and add the oil cooler from a 1.8 engine.
