The Check Engine Light (CEL) can turn on for various reasons, with a faulty catalytic converter being one of the most common causes, especially when P0420/P0430/P0042 codes are present. When the catalytic converter's efficiency drops or it gets damaged, exhaust pollutants are not fully converted, triggering the CEL.

Common signs of a faulty catalytic converter include:

1. Check Engine Light (CEL): Common codes like P0420 (Catalyst System Efficiency Below Threshold Bank 1) and/or P0430 may appear.
2. Lack of Power: Noticeable power drop after the vehicle warms up.
3. Speed Limitation: Difficulty in exceeding speeds of 30-40 mph (48-64 km/h).
4. Unpleasant Odors: A rotten egg smell coming from the exhaust.

If you detect these codes, our product is the ideal solution.

Note: Don’t just rely on using an extender, as they often don’t work. Our Mini Catalizador CEL FIX is an innovative solution that incorporates a built-in mini catalytic converter, meeting European 5 standards. It is specifically designed to effectively resolve CEL issues caused by high-flow catalytic converters (HIFLOW Cat), deleted catalytic converters, or faulty catalytic converters.

How it Works:

First, by adjusting the position of the second O2 sensor, moving it away from the direct exhaust flow, our built-in mini catalytic converter starts to function. Its operation is similar to a traditional catalytic converter, converting harmful exhaust gases into harmless substances. This effectively "tricks" the ECU into thinking the catalytic converter is still working, helping eliminate the annoying Check Engine Light (CEL) and resolve persistent error codes such as P0420 and P0430. This solution is especially suitable for vehicles with modified exhaust systems, vehicles that have deleted the stock catalytic converter, or those with faulty catalytic converters.

Benefits:

1. Optimizes Fuel Efficiency: A worn-out oxygen sensor can lead to excessive gasoline consumption and accelerate catalytic converter damage. Our Mini Catalizador helps optimize fuel efficiency, reduces emissions, and makes the engine more eco-friendly.
2. Emission Compliance: In regions with emission inspection requirements, a faulty CEL and O2 sensor may lead to inspection failure. Our product eliminates the CEL light, ensuring your vehicle complies with emission standards and passes inspections smoothly.
3. Solves Common Fault Codes: Our solution addresses common fault codes like P0420, P0042, and P0430, ensuring your vehicle runs smoothly and reducing the risk of more significant problems.
   

Overall, the Mini Catalizador CEL FIX provides an easy and effective solution for modified, deleted, or faulty catalytic converter vehicles, ensuring emission compliance and optimizing vehicle performance.

The Mini Catalizador is made from T-304 stainless steel, which offers excellent corrosion resistance, rust resistance, anti-flaking, and anti-bubbling properties.

Compared to other similar products, the advantages of Mini Catalizador include:

Material: The Mini Catalizador uses T-304 stainless steel, while some other products may use galvanized carbon steel filled with steel wool. Galvanized carbon steel can bubble, flake, and rust in high-temperature environments, while T-304 stainless steel has better high-temperature performance and corrosion resistance, allowing it to operate stably at temperatures exceeding 620°F.

Durability: Due to the use of high-quality stainless steel, the Mini Catalizador will not rust, corrode, or suffer other damage, making it more durable than many cheaper products. This reduces issues caused by metal corrosion.

Efficiency: The Mini Catalizador is equipped with a three-way ceramic honeycomb element coated with platinum, rhodium, and palladium, which effectively converts harmful exhaust gases, just like the vehicle's original catalytic converter. This helps eliminate oxygen sensor error lights (CEL). In contrast, some cheaper products may lack this conversion efficiency, leading to more frequent failures.

Easy Installation: The Mini Catalizador is very easy to install, requiring no welding or cutting—simply screw it into the existing O2 sensor interface. This makes it more convenient than other products that require complicated installation processes.

Mini Catalizador is a universal product designed to fit O2 sensor interfaces with M18 x 1.5mm threads, compatible with 99% of vehicles on the market, including but not limited to BMW, Audi, Toyota, Nissan, Honda, Ford, Chevy, Subaru, Mazda, Volkswagen, Mitsubishi, Hyundai, Kia, Lexus, Chrysler, Dodge, and more.

Based on your exhaust system layout and available space, choosing the right Mini Catalizador spacer angle is crucial. We now offer five angle options: 0° (straight), 45°, 45° Pro, 90°, and 90° Pro, all compatible with vehicles that have M18 x 1.5mm O2 sensor bungs. Each angle suits different installation conditions:

0° (Straight):
Ideal for vehicles with sufficient straight space in the exhaust system, offering simple and direct installation.

45°:
Suitable for exhaust systems with limited space, helping to adjust the O2 sensor position for a proper fit.

45° Pro:
Upgraded version of the 45° design, optimized for better performance and a higher success rate in resolving check engine lights, while still fitting well in moderately tight spaces.

90°:
Best for tight or hard-to-reach areas, providing flexibility for installation in compact spaces.

90° Pro:
Upgraded version of the 90° design, featuring enhanced internal structure for improved performance and higher success rate in resolving check engine lights, especially on more sensitive or modern vehicles.

For the best fit, choose the angle that matches your vehicle's exhaust system layout. If you're unsure, it's recommended to consult your mechanic, who can suggest the most suitable option based on your vehicle’s specific needs.

The number you need depends on your vehicle’s exhaust system:
Single exhaust pipe: You need 1 Mini Catalizador
Dual exhaust pipes / V6 / V8 engine: You need 2 Mini Catalizadores (one for each exhaust pipe)

💡 Simple rule of thumb: Count your exhaust pipes — get one Mini Catalizador for each.

If you're unsure, it's best to consult a professional mechanic to ensure you purchase the correct quantity.

Installation Steps:

• Jack up car if necessary, find extended bung which need to replace.
• Loosen old oxygen sensor spacer, bolt it on our new sensor spacer.
• Bolt new sensor spacer to pipe by hand firstly. Tighten with a wrench.
