Oiling System for BMW G82 M4 S58 3.0L

When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system  baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain system comes complete with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

Features:

• 6061-T6 billet machined body, anodized black for lasting protection and appearance
• Strategically positioned 4 chamber baffle system maximizes oil / air separation 
• Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
• Sealed with a pre-installed viton O-Ring
• Includes 2.5mm allen key to remove baffle plates for cleaning
• Engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can
• Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
• Optional use drain hole - drain kit included!
• Universal mounting kit

The factory G8X oil filter housing cap is made of plastic which, by nature of the material, dissipates heat poorly and is prone to failure over repeated heat cycles. By contrast to the OEM unit, our cap is constructed from 6061-T6 aircraft-grade aluminum which promises two functional benefits: greater longevity and cooler running throughout its life cycle.

So too will the oil itself benefit: By getting your oil up to temperature quickly, but tangentially evacuating excess heat, the aluminum oil filter housing cap will help your fluid operate within its working range while effectively preventing thermal breakdown.

Each cap has been meticulously manufactured on a DMG Mori 5-Axis with specially sourced tooling to achieve some of the cap's intricate details. Anodized, the housing cap’s details are happily preserved but offer up a valuable way for an enthusiast to express their individuality. Four colors are available at launch to maximize choice: Ferrari Red, Royal Blue, Hard Coat Clear, and Hard Coat Black.

Appropriately, our latest livery box echoes a Gulf theme—echoing our motorsport intent and ties to the culture that has inspired us to create from the beginning.
