New Release: Future Classic G8X (S58) Oil Filter Housing Caps

Modify with Purpose. 2021 represented a year of ideation and testing behind the scenes for Future Classic, the result of which will be several exciting additions to our current catalog. That said, there were also plenty of ideas that were scrapped—not because they wouldn’t have been good—but because a well-engineered, motorsport-worthy product should be both beautiful and purposeful, not just the former. That critical duality has been a cornerstone of FC’s manufacturing arm. Simply put, we only make parts that we would be proud to put on our own cars.

3D printed housing cap versus the first raw production piece

The first component that we aimed to improve is the factory oil filter housing for S55, S58, S65, and S63-equipped BMW models. Across the range, the factory 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.

We leveraged 3D printing to prototype, which helped us move quickly through testing and, subsequently the first production piece.

The First of Many

The first of the four caps we manufactured was a decision of timing. The G8X (S58) is a new platform for the entire BMW aftermarket, and as such, many owners are just now passing break-in mileage. Since the S58’s oil filter housing sits at the back of the motor, there’s no better time to perform this mod than when you have to change your oil anyway. We were grateful for the opportunity to prototype and test on IND’s G82 M4—one of the first in our area—so that we could get a production component finished while many still waited for their cars to arrive.

Material and Choice

Why Aluminum? Because of aluminum’s propensity to handle and dissipate heat, it is an excellent material from which to build our oil filter housing caps. 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 (at the threshold where your motor oil will degrade and lose viscocity). It is largely the reason why heat sensitive components, like your radiator, are constructed from the same material.

Function aside, we wanted to create a product with visual impact. Holding these caps in hand, it’s immediately apparent that each of them echo our commitment to the smallest aesthetic details. Special CNC tools were specifically sourced to accomplish exactly that and, as a result, each cap is a marvel right out of the DMG Mori 5-Axis. 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.

The Finishing Touch

It wouldn't be a complete Future Classic product drop without a brand new livery box. Given the function of this component, we chose to fashion the oil filter housing box with a Gulf-inspired aesthetic. For the uninitiated, the backstory of the livery is proudly featured on the top side of the box.

All said and done, what began as an exercise to expand our product line eventually turned into an emotionally evocative experience. And, simply put, it's that emotional connection to what we do that ensures we produce exciting components for discerning enthusiasts. Much more to come soon.
