Quick Answer: When ordering ignition coils for Haval vehicles in bulk, the most common mistake is assuming one coil fits all engines. The OS1205 OSRAM ignition coil (OE# 273013C000 / 273013C010) has proven cross-compatibility with several Haval models using Hyundai-derived powertrains, but always verify coil length, connector type, and primary/secondary resistance before placing a wholesale order.
The Bulk Buying Dilemma
You’re stocking shelves for a fleet of Haval H6s, Jolions, and Big Dogs. The ignition coils on these vehicles have a reputation for intermittent misfires around 60,000 km. You’ve seen the prices from dealerships — ¥180–250 per unit in China, double that overseas. Aftermarket copies from local suppliers? Hit-or-miss. Some last 20,000 km; others die in half that.
A workshop in Tashkent recently ordered 200 coils — half of them wrong. The supplier had listed them as “fits Haval H6 2017–2022” but didn’t distinguish between the 1.5T GW4G15 engine and the 2.0T GW4C20. Different coil length, different dwell time. The result: 100 units returned, shipping costs eaten, and a burned relationship.
That’s the reality of B2B parts sourcing for Haval — a brand that shares platforms with Hyundai, Mitsubishi, and even Great Wall’s own engines. If you’re looking at the OS1205 OSRAM ignition coil, which is originally listed for Hyundai (273013C000 / 273013C010), the fitment logic is sound: many Haval models use the same Mitsubishi-derived 4G-series engines or Hyundai’s G4-series blocks. But “fits” doesn’t mean “plug-and-play” in every case.
What to Check Before Ordering — Checklist
Here is a five-point pre-order checklist designed for bulk buyers. Run through it before you commit to any container.
1. Engine Code Verification
Haval uses a mix of engine families:
- GW4G15 (1.5L turbo) — used in H6, Jolion, M6
- GW4C20 (2.0L turbo) — H9, H6 GT, Poer
- 4G63 / 4G69 (older Mitsubishi-derived) — H3, H5
- G4F series (Hyundai-derived) — early Jolion, H2
The OS1205 ignition coil fits engines with a 0.75–0.85 mm air gap, a primary resistance of 0.5–0.6 Ω, and a secondary resistance of 7–8 kΩ. That lines up with the GW4G15 and some Hyundai-derived G4 engines. It will not fit the GW4C20, which uses a longer coil body.
2. Connector Type and Pinout
Haval ignition coil connectors evolved over generations. First-generation H6 (2011–2016) used JPT connectors; later models switched to a smaller GT connector. The OS1205 uses a standard 3-pin JPT (Japan-type) — common on Hyundai, Kia, and early Haval. If your fleet is 2018+ Jolion, you’ll need a different coil.
3. Physical Dimensions and Mounting
Measure the coil body length and the rubber boot depth. The OS1205 has a body length of 126 mm and a boot length of 55 mm. This matches Haval 1.5T engines (GW4G15) perfectly. The 2.0T engines require a 138 mm body. Even a 10 mm difference can prevent the coil from seating into the spark plug well, causing arcing.
4. Electrical Specs vs. Original
Check the published specs against the Haval OEM part number. For a 2019 Haval H6 1.5T, the OEM coil reads primary 0.55 Ω, secondary 7.2 kΩ. The OS1205 reads 0.55 Ω / 7.5 kΩ — well within tolerance. If a supplier won’t share resistance values, pass.
5. Batch Consistency for Bulk Orders
When ordering 200–500 coils, ask for batch test results. Sampled resistance variations should not exceed ±5%. A single bad batch can cripple your warranty margin. Tier-one OSRAM manufacturing (the brand behind OS1205) typically ships with batch test certificates. Insist on them.
OE vs Aftermarket: Where the OS1205 Fits
| Factor | OEM Haval Coil (1.5T) | OS1205 OSRAM | Generic $8 China Coil |
|---|---|---|---|
| Primary Resistance | 0.55 Ω | 0.55 Ω | 0.40–0.70 Ω (wild) |
| Secondary Resistance | 7.2 kΩ | 7.5 kΩ | 5–11 kΩ (unstable) |
| Boot Material | Silicone rubber | Silicone rubber | EPDM (cracks in 1 yr) |
| Core Winding | Copper | Copper | Copper-clad aluminum |
| Batch QC | In-house | ISO/TS 16949 | Often none |
| Price per unit (bulk) | ¥120–150 | ¥45–60 | ¥15–25 |
The OS1205 lands in a sweet spot: near-OEM quality at one-third the price. For B2B buyers servicing Haval fleets, this means a margin of 100–150% after rebranding or direct resale, while still beating dealership pricing. The generic coils will save you ¥20 more per unit — but expect field failure rates of 8–12% within the first year. That eats your net profit faster than you’d think.
Where to Buy for B2B — Practical Advice
- Source from verified OSRAM distributors in China (Guangzhou, Shanghai). The OS1205 is not a grey-market part; it’s produced under license and exported globally. Request a factory audit or third-party inspection report.
- Minimum order quantities typically start at 50 pieces for the OS1205. For larger runs (500+), negotiate an MOQ discount of 8–12%.
- Avoid platforms that drop-ship single units. B2B buyers need consistent stock, traceable lot numbers, and the ability to return defective units within 30 days.
- Shipping note: Ignition coils are lightweight but bulky. 200 pieces fill about one cubic meter. Air freight from Shenzhen to Dubai or Lagos runs roughly $400–600. Sea freight is cheaper but adds 4 weeks.
Bottom Line
For Haval 1.5T engines and any Hyundai-derived powertrain in the Haval lineup, the OS1205 | OSRAM Ignition Coil | Fits Hyundai | OE# 273013C000 273013C010 OS1205 ignition coil delivers OEM-grade reliability at a wholesale price that leaves room for profit. The checklist above — engine code, connector, dimensions, resistance, batch testing — is your firewall against the wrong parts reaching your customers.
Ordering bulk ignition coils is not about finding the cheapest unit. It’s about finding the most consistent unit. The OS1205 passes that test. If your fleet includes older Haval 2.0T or Mitsubishi-derived engines, keep looking — this coil isn’t for them. But for the vast majority of 1.5L Haval vehicles sold globally between 2015 and 2024, the OS1205 | OSRAM Ignition Coil | Fits Hyundai | OE# 273013C000 273013C010 is the part to stock.
Have a specific Haval engine code? Run it against the OS1205 specs before you sign the PO. A ten-minute cross-check can save you a truckload of returns.
