If you’ve rebuilt enough turbo four-cylinders, you start recognizing parts that simply behave. This set is one of them. It’s built for the G4KH 2.0T and, to be honest, it strikes a practical balance of OEM discipline with tuner-friendly resilience.
Turbo engines are running hotter, tolerances are tighter, and coolant formulations keep evolving. The upshot? MLS head gaskets with smarter coatings, molded rubber for breathers, and graphite where thermal cycling is brutal. Many customers say they’re seeing fewer cold-start weeps—largely down to better beading and coatings. It seems that Full Gasket Set 209102GO00AVV for HYUNDAI G4KH 2.0T lands right there.
| Part Number | 209102GO00AVV | Engine | HYUNDAI G4KH 2.0T (gasoline, turbo) |
| Head Gasket | MLS (3–5 layers), FKM coated, beaded fire ring | Bore Ø | ≈86 mm (real-world use may vary) |
| Thickness (std) | ≈1.0 mm (options on request) | Temp Range | -40 to 250 °C contact; peaks higher at fire ring |
| Other Gaskets | Valve cover (molded rubber), intake/exhaust (graphite/steel), stem seals (FKM) | Certs | IATF 16949, ISO 9001; RoHS/REACH compliant |
Materials: stainless MLS stack, FKM/Viton coatings, graphite composite carriers, NBR/FKM molded seals. Methods: multi-stage stamping and roll-beading, laser cutting for ports, vulcanization for rubber, adhesive lamination where needed. Testing: sealability per ASTM F37, compression set per ASTM D395, surface RA checks (≤3.2 μm at mating faces), pressure/thermal cycling; some lots even get helium leak tests. Service life? In fleet conditions we’ve seen ≈100–150k km without drama, assuming flatness and torque are within spec.
Address for origin and QC traceability: 289 Heping East Road, Chang’an District, Shijiazhuang City, Hebei Province, China.
| Vendor | Materials/Coating | Certs | Lead Time | Notes |
|---|---|---|---|---|
| Oujia (this set) | MLS + FKM, graphite, molded FKM seals | IATF 16949, ISO 9001 | ≈7–15 days | Value/performance sweet spot |
| OEM dealer set | MLS, OE coatings | OEM tier | Stock-dependent | Highest price, bulletproof fit |
| Budget aftermarket | Mixed composites | Varies | Fast | Watch coating quality, compression set |
Options: head-gasket thickness (≈0.8–1.3 mm), bore tweaks, fire-ring emboss depth, FKM/NBR selections for specific fuels/coolants, branded packaging. MOQ is sensible for workshops. Actually, I’d spec FKM stem seals if your cars see long idles.
Fleet shop: 12 cars, G4KH 2.0T rebuilds. After 60k km, oil seepage incidents dropped by ≈80% versus a previous composite set—mostly at the valve cover and timing cover transitions.
Tuner garage: Track-day sedan, conservative tune, ~1.5 bar peak. The Full Gasket Set 209102GO00AVV for HYUNDAI G4KH 2.0T held steady after three weekends; head retorque checks were uneventful. Not scientific, but encouraging.
Bottom line: if you want a dependable, standards-backed kit with smart materials—and you’re mindful of surface prep and torque—the Full Gasket Set 209102GO00AVV for HYUNDAI G4KH 2.0T deserves a spot on your bench.
