Micro-Cat - Micro Catalytic Converter
SKU: M3-200
LOOKING FOR A CHEAP WAY TO GET AROUND AN CHECK ENGINE LIGHT (CEL) AFTER INSTALLING A HIGH-FLOW OR NON-CAT EXHAUST ON A PETROL CAR?
These micro-cats screw into the O2 sensor port of an exhaust and contain a small catalytic converter. This allows the O2 sensor to be plugged into the back of them and assist with preventing CEL (Check Engine Lights).
They are a simple screw-in installation designed for DIY install. With these in place it's enough for most cars to avoid a check engine light, however it cannot be guaranteed as some makes / models have higher sensitivity for catalityc converter.
Two versions are available:
- 90-degree (O2 sensor sits parallel to exhaust)
- Straight (O2 sensor sits perpendicular to exhaust)
SOLD INDIVIDUALLY - NOT AS A PAIR
