About

Who we are

In short

MiniCats SA is a South African online retailer that sells one thing properly: 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.

What we sell, and what we don't

We stock a single 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 tells you how to check your own thread and clearance in about five minutes, and it tells you plainly when the answer is that this part is wrong for your car.

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 R199 and have the light come back on 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.
