11427508970 BMW - OIL FILTER HOUSING GASKETS: OEM Fit?

Field Notes on the 11427508970 BMW Oil Filter Housing Gaskets

If you wrench on modern BMWs, you already know the usual suspects: oil weep from the housing, a burnt-oil smell on warm-up, and that slightly embarrassing driveway spot. The fix is often the 11427508970 BMW - OIL FILTER HOUSING GASKETS. I’ve watched dozens of shops treat this as a “while you’re in there” service, and honestly, it saves callbacks. Below is the insider’s look—tech specs, test data, how it’s made, plus some real-world context you can use.

What it fits and why it fails

Part no. 11-42-7-508-970, new and original-fit geometry, suitable for both left- and right-hand drive models. Coverage includes: E81, E82, E87, E87 LCI, E88, E46, E90, E90 LCI, E91, E91 LCI, E92, E92 LCI, E93, E93 LCI, E60 LCI, E61 LCI, X1 (E84), X3 (E83/E83 LCI), Z4 (E85). Heat cycles plus modern low-ash oils can harden weaker elastomers. A proper elastomer blend (FKM/Viton or equivalent) resists hot oil, shear, and micro-movement at the housing flange.

Quick spec sheet

Product	11427508970 BMW - OIL FILTER HOUSING GASKETS (11-42-7-508-970)
Material	High-temp elastomer: FKM (Viton) or equivalent per ASTM D2000, oil-resistant
Hardness	≈ 70 ± 5 Shore A (ASTM D2240)
Temp range	-30°C to +200°C (real-world may vary with oil type/duty)
Compression set	≤ 25% @ 150°C, 22h (ASTM D395, typical)
Leak test	No visible seep @ up to 5–6 bar bench pressure (fixture test)
Service life	Around 60k–100k miles with proper oil intervals

How it’s made (brief process flow)

Materials: compounded FKM/NBR with heat/oxidation inhibitors.
Molding: precision compression or injection molds; flash trimmed; post-cured for stability.
Dimensional control: ±0.10 mm typical on critical sealing lands, CNC-checked.
Testing: hardness (ASTM D2240), tensile/elongation (ASTM D412), compression set (ASTM D395), thermal aging (ASTM D573), oil immersion (ASTM D471).
Quality system: automotive-line production with IATF 16949-style controls (documentation available on request).

Use cases and shop notes

Daily drivers, tuned N52/N54 weekend cars, fleet taxis—same story. Many customers say swapping the 11427508970 BMW - OIL FILTER HOUSING GASKETS during belt/alternator or coolant service is “cheap insurance.” I’ve seen surprising oil misting stopped cold after a proper surface clean, torque sequence, and a fresh gasket.

Vendor comparison (real-world expectations)

Option	Material/Spec	Testing	Price	Notes
YJM Seal (OES-grade)	FKM or equivalent; tight tolerances	ASTM D2000/D395/D471 set run, leak bench	Mid	Balanced performance vs. cost; strong availability
Generic aftermarket (budget)	NBR, variable batches	Limited QA	Low	May harden sooner; watch for seep in hot climates
OEM dealer	BMW OE material	Full OE validation	High	Excellent fit; premium cost

Customization and logistics

Need private-label packaging, a specific durometer, or kit bundling with bolts/O-rings? It’s doable. Typical lead times run 2–4 weeks for batch repeats. Origin: JULU INDUSTRY AREA, XINGTAI CITY, HEBEI PROVINCE, CHINA 055250. To be honest, stocking a dozen sets saves headaches during seasonal rushes.

Case snapshots

E90 325i taxi fleet: after switching to 11427508970 BMW - OIL FILTER HOUSING GASKETS with FKM, leak callbacks fell ≈ 70% over six months.
E84 X1 in hot climate: previous NBR gasket wept at ~10k mi; FKM replacement sealed clean past 25k mi (so far).
