Honest advice first
Every guide puts diagnosis before the purchase. If an exhaust leak, a lazy sensor or a misfire is the real problem, the guides say so — even when that means you do not need a spacer.
Diagnose a P0420About MiniCats SA
One part, sold properly, from Johannesburg
MiniCats SA is a South African online retailer that sells one thing: mini catalytic converter O₂ sensor spacers. Stock sits in Johannesburg, Gauteng, and orders go out on a local courier — not a three-week wait on an overseas parcel.
In short
We stock a single part, so we can be specific about it
Who we are
MiniCats SA sells one part: a stainless steel M18 × 1.5 oxygen sensor spacer with a miniature catalyst element inside it. We do not sell catalytic converters, oxygen sensors, ECU tunes or exhaust fabrication.
Selling one part means we can be specific about it. The fitment guide walks you through the four checks — thread, clearance, wire slack and one spacer per downstream sensor — and it tells you plainly when the answer is that this part is wrong for your car.
What we sell
- Stainless steel M18 × 1.5 O₂ sensor spacer, 58 mm long
- A miniature catalyst element and restrictor disc inside the chamber
- R350 each — your oxygen sensor is not included
What we don't
- Catalytic converters
- Oxygen sensors
- ECU tunes
- Exhaust fabrication

Where to find usFit checked before you buy
Send the part number off your downstream oxygen sensor and we will tell you whether the M18 × 1.5 spacer fits — including when the answer is no.
Ask about your carWhy we are careful
Why the guides are honest about the limits
An O₂ sensor spacer changes what your downstream sensor reports. It does not repair a catalytic converter and it does not reduce what leaves your tailpipe. Plenty of listings for this part imply otherwise. We would rather lose a sale to someone whose real problem is an exhaust leak than take their R350 and have the light come back a week later.
That is why every guide on this site ranks diagnosis before purchase, and why the comparison guide openly describes the cases where a new catalytic converter or an ECU tune is the better answer.
