Performance Engine Oil Radiator Upgrade for BMW 3 Series E92 Coupe 2011 to 2013
Keep temperatures in check on spirited drives and track days with this Dinan large-format engine oil radiator package. Built for enthusiasts who push their 3 Series hard, this comprehensive heat exchanger kit slashes lubricant temps, improves consistency and protects the turbocharged straight-six during repeated hot laps and fast-road use.
This direct-fit solution is designed for vehicles that already have the OE auxiliary cooler and retain the original front valance. It locates neatly in the factory position and works seamlessly with the stock ducting for clean airflow management and a tidy OEM-plus appearance.
Why this cooling upgrade works
- Massively increased core capacity for far greater thermal headroom under sustained load
- 414 square inches of tube area versus 112.5 square inches on the OE unit for stronger heat rejection
- Purposeful inlet ducting to feed the core efficiently and stabilise operating temperatures
- Enlarged outlet path that vents hot air into the wheel arch to minimise heat soak
- Lightweight convoluted PTFE lines with a tough polyester braid for durability and minimal pressure drop
- Motorsport-grade hose ends and hardware for long-term reliability at high temperature and pressure
- Bolt-in install in the stock location for a clean, factory-style finish
The result is cooler oil, more dependable power delivery and improved engine protection when you are flat out. It helps resist heat fade and the limp-home intervention that can interrupt your session when temperatures climb.
Vehicle compatibility
For cars with the original auxiliary cooler and standard front bumper:
- BMW 3 Series 335i Coupe E92 2011, 2012, 2013
- BMW 3 Series 335i xDrive Coupe E92 2011, 2012, 2013
