Product Overview
Upgrade your vehicle’s exhaust system with our premium Gasoline Particulate Filters (GPF). Designed to reduce harmful emissions while maintaining optimal engine performance, our GPFs are compatible with a wide range of gasoline-powered vehicles. Whether you need a direct-fit replacement or a universal upgrade, our filters deliver efficient particulate trapping without restricting exhaust flow.
Purchasing notice
1. The product price only includes the price of 1 pc.
2. If you need a large batch, please contact our customer service
3.Please replace the catalyst of the original size and do not modify it
4.Due to increased emissions standards, these items are not certified for sale in California, New York, Maine and Colorado.
5.Support customization
| Comparison Items | Coated GPF | Uncoated GPF |
|---|---|---|
| Main Function | Particulate filtration + Catalytic conversion (oxidizes CO/HC) | Physical particulate filtration only |
| Filtration Efficiency | Higher (90%+, captures nano-sized particles) | Lower (70-85%, relies on physical interception) |
| Regeneration Capability | Efficient passive regeneration (coating catalyzes soot oxidation) | Relies on high exhaust temperature for natural oxidation, slower regeneration |
| Emission Control | Reduces PM, CO and HC emissions (similar to three-way catalyst) | Only reduces PM emissions |
| Backpressure Impact | Slightly higher (coating increases flow resistance) | Lower (no coating, better flow) |
| Cost | Higher cost (precious metal coating adds 30-50% cost) | Lower cost (ceramic substrate only) |
| Lifespan | Longer lifespan (100,000-150,000 km) | Shorter lifespan (more affected by carbon buildup) |
| Maintenance | Minimal maintenance required | Requires frequent backpressure checks |
We strive to make your shopping experience seamless with clear shipping and return guidelines. Please review our policies below.
Returns Policy
We offer a 14-day return policy from the date of delivery. To be eligible for a return:
- Items must be in original condition - unused, unworn, with tags and packaging
- Proof of purchase (receipt/invoice) is required
- Certain items are exempt from returns (see exceptions below)
To initiate a return, please contact us at svipcatcatalytics@gmail.com. We will provide a return shipping address and instructions. Items returned without prior authorization will not be accepted.
Non-Returnable Items:
- Incorrectly ordered car model sizes
- Products damaged due to illegal modifications or improper installation
- Catalysts with welding defects or installation-caused leaks
- Sale items and gift cards
For damaged, defective, or incorrect items, please contact us immediately upon receipt. Refunds are processed within 10 business days after we receive and inspect your return.
Shipping Policy
We utilize DDP air shipping (Delivered Duty Paid) which includes all customs clearance and import taxes:
- UK Delivery: 8-12 business days
- EU Delivery: 12-15 business days
- US Delivery: 15 business days
Tracking information becomes available once your package is transferred to our local courier partners (UPS/FEDEX/DHL). Please note:
- Initial air freight transit does not provide tracking
- Customs inspections may cause unexpected delays
- DDP means no additional fees will be charged upon delivery
For expedited shipping options or any shipping inquiries, please contact us at svipcatcatalytics@gmail.com.
The catalyst reacts based on exhaust temperature. For best performance, install within 50cm of the engine.

⚠ SAFETY OPERATION | ENGINE LINKAGE | BACKPRESSURE WARNING ⚠
I. DPF Handling Specifications
Handle with care
▶ Cordierite material is highly brittle - no impact or dropping!
▶ Always support from bottom, never lift by sensors or pipes.
No hammering
▶ Absolutely no hammering, prying or forced installation!
▶ Deformation/cracks will void warranty.
II. System Compatibility Check (Engine + Exhaust)
Mandatory backpressure inspection
▶ Must check before installation:
• Turbocharger oil leakage ✅
• Exhaust pipe dents/blockages (especially catalytic converter) 🔺
• EGR valve sticking or cooler carbon buildup ✅
▶ Abnormal backpressure causes:
→ DPF regeneration failure 🔺
→ Substrate melting/cracking 🔺
Engine health requirements
• Fix oil burning, injector leaks, cylinder misfires
• Installing DPF with existing issues = immediate clogging!
III. Installation Standards
Sealing & Compatibility
• Ensure gaskets are intact + sealing surfaces oil-free (leaks cause pressure fluctuations) 🔺
• Part number must 100% match vehicle/engine model
Sensor Protection
• Prevent wire strain and connector contamination
• Must calibrate differential pressure sensor with diagnostic tool (critical for backpressure monitoring) 🔺
Yes, we do.
1. Vanadium-based (V₂O₅-WO₃/TiO₂)
Active component: Vanadium pentoxide (V₂O₅) on titanium dioxide (TiO₂) with tungsten (WO₃) for thermal stability.
Temperature range:
300–400°C (medium-high), ideal for coal plants, industrial boilers.
Features:
• High NOₓ conversion (>90%)
• Low sulfur resistance (SO₂ oxidizes to SO₃)
• Toxic components require careful disposal
2. Iron-based (Fe-ZSM-5 etc.)
Active component: Iron oxides/ions on zeolite molecular sieves.
Temperature range:
250–450°C (medium-high), weaker at low temps.
Features:
• Better sulfur tolerance
• Non-toxic, easier disposal
• Requires higher temps for efficiency
3. Copper-based (Cu-SSZ-13, Cu-ZSM-5)
Active component: Copper ions on small-pore zeolites.
Temperature range:
200–500°C (wide), excels at 200–300°C.
Features:
• Excellent low-temperature performance
• High resistance to sulfur/water poisoning
• Stable up to 550°C
g/cft.Pt:
g = grams (mass)
cft = cubic feet (1 cft ≈ 28.3 liters)
Pt = Platinum (active component in DOCs)
Definition: Platinum loading per cubic foot of catalyst substrate.
Examples:
• 10g/cft.Pt = 10 grams platinum per cubic foot
• 20g/cft.Pt = higher platinum loading
10g/cft.Pt:
For lower emissions standards (e.g., Euro V) or cost-sensitive applications.
20g/cft.Pt:
For strict standards (Euro VI), heavy-duty vehicles, or extended lifespan requirements.
SDPF (SCR-coated Diesel Particulate Filter) integrates SCR (Selective Catalytic Reduction) and DPF functions into one unit, primarily used to meet strict emissions standards like Euro 6.
We provide multiple options:
• Express: FEDEX, DHL, UPS, TNT (door-to-door)
• DDP: Includes customs clearance + duties + delivery
• Sea/Air freight: To airport/port (customer pickup)
• Small parcel: Cainiao, YunExpress, USPS etc.
