Dinan High Capacity Oil Cooler System Upgrade for BMW 335i/335i xDrive E92/E93 (2007-2010, N54) - For Factory Oil Cooler Cars

Uprated Engine Oil Cooling Kit for BMW 335i N54 - Dinan quality for OE oil cooler cars

Stop oil temperature creep on your 3 Series and keep power consistent. This Dinan performance oil cooling upgrade is the proven solution for BMW 335i owners who drive hard, run a remap, or enjoy track days and fast road use. By increasing capacity and improving heat rejection via a more efficient heat exchanger, this kit helps the N54 twin turbo straight-six maintain stable temps, protecting the engine and delivering repeatable performance.

If you own an E92 coupe or E93 convertible with the original BMW oil cooler from factory, this is the direct-fit, bolt-on upgrade you want. Ideal for tuned cars, Stage 1 and Stage 2 software, hybrid turbo builds, spirited B-road blasts and summer motorway traffic. Expect stronger back-to-back pulls, reduced thermal soak, and less likelihood of over-temp limp mode when you’re pushing on.

Why this uprated oil cooling kit stands out

• Helps keep oil temperatures in check under sustained load and high ambient conditions
• Supports reliable power delivery on remapped and modified N54 engines
• Direct upgrade for vehicles that already have the OE oil cooler hardware
• Designed by Dinan for OEM-level fit, finish and durability
• Confidence-inspiring cooling for road, track day and fast road use
