Dinan Oil Cooling Package for BMW 3 Series E92 335i (2011–2013)

Keep your turbocharged six running strong with Dinan’s premium engine oil cooling solution for the BMW E92 335i. This performance-focused oil radiator upgrade is engineered for 2011, 2012 and 2013 two-door models equipped from the factory with an OE oil cooler, whether rear-wheel-drive or xDrive all-wheel-drive, and with the M Sport front bumper styling.

If you’re experiencing soaring oil temps on spirited drives, during summer heat, or on track days, this Dinan kit provides the extra temperature margin you need for consistent power delivery and long-term engine protection. We run this setup on our own cars and our customers repeatedly report cooler, more stable oil temperatures and dependable performance session after session.
