BMW Engine Oil Filler Cap with Seal – Fits 1 Series, 3 Series, 5 Series, 6 Series, 7 Series, X3, X5, X6, Z4 – Replaces OEM Part No. 11121715318

Restore your BMW’s factory-tight seal and eliminate unwanted leaks with this high-quality Engine Oil Filler Cap Gasket, engineered to exceed OEM specifications. Over time, the original rubber gasket becomes brittle, flattened, or cracked from constant heat cycling. This leads to oil misting around the filler neck, vacuum leaks, inconsistent idle, and even gradual oil pressure loss.

This upgraded replacement gasket brings your engine back to proper sealing performance by ensuring a tight, uniform fit between the cap and valve cover. The result? A cleaner engine bay, stabilized oil pressure, improved efficiency, and long-term protection of vital engine components.

Made from heat-resistant, oil-resistant rubber, it’s designed to withstand the demanding environment of BMW engines—preventing the common seepage and residue buildup you’ll often find on aging vehicles. This is one of the simplest, most effective maintenance items you can replace to keep your BMW running smoothly and cleanly for years to come.
