Uprated Engine Oil Cooling Package for BMW E90 335i and 335xi N54
Give your E90 3 Series the oil temperature control it deserves. This Dinan uprated oil cooling package is a proven solution for the N54 twin turbo straight six, delivering far better thermal stability than the standard equipment on vehicles already supplied with an OEM oil cooler. Expect stronger, repeatable performance on spirited road drives and track days, with reduced oil temps and far less power fade when the going gets hot.
Why you want this on your N54
- Lower running temperatures for the lubricating system during hard use
- More consistent power delivery on back-to-back pulls and long sessions
- Improved protection for bearings, turbochargers and seals under high load
- Ideal for remapped Stage 1 and Stage 2 cars, hybrid turbo builds and fast road setups
- Direct upgrade path for models already equipped with a factory oil cooler
How it improves cooling
Dinan’s high capacity heat exchanger increases effective core volume and surface area while optimising flow. The result is superior heat rejection and more stable oil temperatures under sustained boost. That means fewer hot-weather power drop offs, less thermal soak and more confidence to push your BMW without the ECU dialling things back.
Key highlights
- Significant oil temp reduction versus the standard cooler on like-for-like runs
- Enhanced thermal management for tuned N54 applications
- Quality engineering from a trusted BMW performance brand
- Built for reliability on fast road, track day and motorway use
Vehicle applications
- BMW 3 Series E90 335i and 335xi xDrive saloon, 2007 to 2008
- N54 twin turbo engine only
- For cars that already have an original equipment oil cooler
Tried and trusted
We have fitted this upgrade on customer builds as well as our own. Feedback is consistently strong, with noticeable drops in oil temperature and far more consistent performance during hard driving. It is a standout reliability upgrade for any serious E90 N54 owner.
