Upgrade your weak plastic S58 oil filter housing cap
The Burger Motorsports billet aluminum S58 oil filter cover directly replaces your weak OE plastic cap for greater protection, ease of removal/install, and great looks under the hood. You can use a 3/8" inch drive ratchet or torque wrench to install and remove. The built-in 32mm hex head does not require a special removal/install tool like the factory cap. Uses the OE oil filter, filter housing o-ring, and filter insert. Anodized for protection. This quality part is a must for any serious BMW owner.
Equipped with an integrated samarium cobalt magnet to capture dangerous metal shavings and particles that would otherwise circulate through your engine oil and bearings. Unlike other oil filter caps that press fit smaller magnets leaving them vulnerable to damage and displacement during engine heat cycles, our magnets are secured in their precisely machined pockets to safely withstand extreme temperatures and pressure.
🔧 Install: After removing the OEM oil filter cap, remove the filter and be sure to remove the plastic oil filter bypass valve and transfer it to the new BMS billet oil filter cap (see below install video). Be sure to replace the exterior o-ring gasket also when installing.

What is billet?
In this case, A billet is a solid block of aluminum (lightweight metal) with a size larger than the part. Excess material from the billet is removed by precision CNC machining, essentially carving the part out of solid aluminum. CNC machined parts are consistently stronger, better looking, and last longer than cheaper cast and plastic versions.
Please note some engine degreasers and harsh cleaners may fade or damage the anodized finish.
