Show original supplier description

The Mazda N3R1-14-700 is a genuine OEM oil cooler engineered for the 2009-2011 Mazda RX-8. This component is crucial for maintaining optimal engine temperatures by cooling the engine oil. Designed for rotary engines, this oil cooler is compatible with both manual and automatic transmission variants of the RX-8, specifically for models with normal power output. It serves as a direct replacement for the original equipment. When replacing oil lines associated with the oil cooler on an RX-8, substantial labor effort is typically required. It is often best undertaken when the engine has been removed from the vehicle, though it can be performed with the engine in place, requiring adequate time and careful attention due to limited access. This is considered an involved project that cannot be rushed.
