FAQ & Support

🚦 1. Trouble Codes & Symptoms

Q1: My car shows codes like P0420 / P0171 / P0138. What do they mean?

These are common codes related to the fuel system or oxygen sensors:

P0420: Catalyst efficiency below threshold
P0171: System too lean
P0138: O2 sensor voltage high

They often indicate a worn oxygen sensor, exhaust leak, or ignition issue. If you're not sure, simply tell us your year, make, model, and engine—we'll check the exact part you need.

Q2: My engine shakes at idle. Is my ignition coil bad?

It's very possible. Common symptoms of a failing ignition coil include:

Rough idle or shaking
Hard cold starts
Poor acceleration
Higher fuel consumption
Misfire popping noise

Tell us your vehicle info—our team can help you identify the cause.

Q3: What are the symptoms of a bad oxygen sensor?

Typical signs include: Check Engine Light on, Increased fuel consumption, Poor acceleration, Strong fuel smell, and Slow throttle response.

Most sensors should be replaced every 80,000–100,000 km.

🔍 2. Fitment & Compatibility

Q4: How do I know which oxygen sensor fits my car?

Just provide: Year, Make, Model, and Engine size.

We'll confirm: Upstream or downstream, Correct connector, Proper reference number, and Federal vs. California emissions compatibility.

Q5: What's the difference between ignition coils?

High-quality aftermarket: Close to Standard but more affordable.

We only offer high-grade, reliable ignition coils.

Q6: How many oxygen sensors does my car have?

Most vehicles have 2–4 sensors (Upstream front and Downstream rear). We can confirm the exact number for your vehicle.

🛒 3. Buying, Quality & Concerns

Q7: Are cheap oxygen sensors reliable?

They work for a short time but usually cause issues like short lifespan, slow response, and frequent check engine lights.

We only sell new, high-quality, fully tested sensors.

Q8: How can I avoid buying a refurbished or used auto part?

Check for scratches on the connector, dirty wiring, or marks on threads.

Our parts are 100% brand new, never refurbished, and fully tested.

🧰 4. Installation & Usage

Q9: Can I install an oxygen sensor myself?

Yes. Difficulty: medium.

You'll need an O2 sensor socket, Anti-seize compound, and a Torque wrench. We recommend clearing fault codes with an OBD scanner after installation.

Q10: Do ignition coils need programming after replacement?

In most vehicles, no programming is required. Just swap the old coil with the new one.

💰 5. Value & Performance

Q11: Your parts cost less than Other accessories. Are they really reliable?

Yes—our parts use the same-grade materials and testing standards as suppliers. Because we don't go through dealer channels, the price is much more affordable.
