Product Information

Wlevate the look and feel of your engine bay with the MaxCap S58 Aluminum Engine Oil & Coolant Cap Set, designed specifically for BMW G87 M2, G80/G81 M3, G82/G83 M4, F97 X3M, and F98 X4M models (2021+). Produced by MaxCap — a premium CNC division from Taiwan known for high-quality BMW cooling system components — and exclusively available through FTP Motorsport, this kit adds a race-inspired aesthetic while providing exceptional durability.

Each cap is CNC-machined from 6061-T6 billet aluminum and finished in a high-strength anodized red coating that resists heat, corrosion, and daily wear. The result is a visually striking, motorsport-focused upgrade that instantly transforms the appearance of your engine bay without compromising factory fitment.

Please note — due to the anodizing process and batch production, minor variations in shade may occur between caps. Each kit is matched as closely as possible, but those with strict colour-matching requirements should consider this before purchasing.

After 3 other BMW workshops couldn't fix the problem with my M3. SouthernBM sorted it. Excellent to deal with, great communication and customer service.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!
