Dinan Uprated High-Capacity Engine Oil Cooler Kit for BMW 1M E82 (2011) N54 | 1 Series M Coupe – Direct-Fit Bolt-On Performance/Motorsport Cooling Upgrade, 2x Volume Heat Exchanger, 414 sq in Core, Track Day Ready

Dinan Uprated Oil Cooling Package for BMW E82 1M Coupe

Stop oil temperatures from spiralling when you push your 1 Series M hard. This Dinan uprated oil cooling package is a proven solution for the 2011 BMW E82 1M, delivering serious thermal control for fast road and track use. By dramatically increasing core capacity and airflow efficiency, it helps keep power consistent, protects the engine during extended sessions, and reduces the chance of the car dropping into reduced power mode when worked hard.

Why it works

The factory arrangement on the 1M can be overwhelmed during spirited driving and circuit work. Dinan’s engineered upgrade offers approximately double the internal volume compared with the OE unit and integrates clever ducting to feed more air through the cooler while allowing hot air to exit cleanly into the fender area. More flow, more surface area, more stability.

Standout benefits

• Big jump in heat rejection for dependable oil temperature control in demanding conditions
• Helps maintain consistent lap times and power delivery during long stints
• Supports tuned and remapped cars that generate more heat under load
• Improves engine longevity by stabilising viscosity and reducing thermal stress
• Ideal for track days, fast road driving, hot weather and repeated high-boost pulls

Technical highlights

• Approximately 2x the volume of the OE cooler for serious thermal headroom
• 414 sq in of cooling tube area versus 112.5 sq in on the factory setup
• Integrated inlet ducting for superior airflow and a larger outlet to vent to the wheel arch
• Installs in the factory location for a tidy, OEM-like finish
• Lightweight convoluted PTFE lines with a polyester braided outer for durability
• Race-grade fittings for confidence under sustained high load
