Mini Catalizador O2 Sensor Spacer CEL FIX P0420/P0042/P0430 Code Universal (90 Degree)
I bought this with very little faith it worked but I will definitely admit I was very wrong. I installed it on my 1999 Toyota Avalon and I didn't clear the CEL just to see if the Catalizador would allow the catalyst test to pass. And it did. A couple weeks ago now and so far no light. I had a bit of an issue with installation but it was a wire length issue more than anything. The 90° fit perfectly but the spacing was an issue due to the short downstream O2 sensor wires. I had to do some adapting to get everything to fit in the factory spot. It works perfectly so far. No complaints about fit or function. It does what it says it does. I just hope it lasts a long time. I will be buying again for sure. Great product!
Well I bought two 90* and two straight Mini Catalizadors, a straight on drivers side and a 90* on passenger side. and yes they fixed my P0420/P0430 codes. But then I got a P0137 so even though I had another 90* I ordered 4-45*s and put a 45* in place of the straight, After 50 miles no codes. Excellent!
Even after putting in a catalytic converter, I couldn't get my engine light to go away for a catalytic converter efficiency, and this fixed it
Even with 90 degree catalizador I had to do a little prying and bending of the down pipe bottom mount tabs. Nothing major. Left down pipe in place and just used a pry bar to get a little extra room to screw in catalizador. It got rid of the P0420 code, cat efficiency, just like it says. But…..now there’s a new code, P0421, takes two long to heat up. I’m thinking if I used the straight catalizador it would heat up faster and not throw the new code. But my hole for the cat is in a place that would than bring the transmission case into play. The O2 sensor won’t go in because it sticks out too far and hits the trans case. Overall I think this helps even out short and long term fuel trim and downstream O2 sensor readings for the downstream O2 sensor once it heats up and engine is running at constant rpm’s. When it’s accelerating or you’re on and off the gas, stop and go traffic, sensor readings are all over the place and eventually engine will throw O2 sensor inconsistency readings error. So if not too long to heat up engine code eventually inconsistency readings engine code. So still thinking over what solution for none mini main cat replacement issue with P0420 cat efficiency error code. But the device did what it said it would do, no more P0420.

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:
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:
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 offer three angle options: 0° (straight), 45°, and 90°, 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.
90°: Best for tight or hard-to-reach areas, providing maximum flexibility for installation.
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 angle 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:
Note: Before installation, make sure all parts of the product are intact, and ensure that the top cover is tightly secured; otherwise, the cover may come loose and be lost.
