Dinan High Capacity Oil Cooler System (Cars without factory oil cooler)(M-Technic bumper)


SKU: D570-0907-1

All orders will include an AutoTalent window decal
The Dinan High Capacity Oil Cooler provides literally twice the volume of the stock unit, as well as 414 sq./in. of cooling tube vs. 112.5, and that's really just the beginning. Nicely integrated inlet ducting provides greater airflow efficiencies and the ventilation of air to the fender well has also been improved with a larger outlet.
The system mounts neatly in the stock location and includes lightweight convoluted PTFE hoses with polyester outer braid fitted with race-quality fittings. 
  • Total Volume Stock: 9.5 oz. / Total Volume Dinan: 19 oz.
  • Stock Surface Area: 45 sq./in. / Dinan Surface Area: 67.5 sq./in.
  • Stock Cooling Tubes: 10 / Dinan Cooling Tubes: 23
  • Stock Tube Length: 90 in. / Dinan Tube Length: 207 in.
  • Stock Tube Area: 112.5 sq./in. / Dinan Tube Area: 414 sq./in.
The results of the oil cooler upgrade are quite significant, with the temperature gauge holding steady even under high load/high boost scenarios. And for those of you who track their cars, even occasionally, the Dinan oil cooler is a must
Special Note: Only for use with M-Technic bumper & cars without a stock oil cooler.
