Spark plug OEM Audi or OEM Mazda

Check out getting rs3 spark plugs if it’ll work.

Audi A3 spark plugs work like a charm. Stage 2+ & fully upgraded supporting hardware.

Since I've owned my 18 S4 i've done almost everything myself:

4 oil changes, spark plugs at 40k, 2 sets of pads and 1 set of rotors, both air filters.

Rx-8 in 3years just did maintence and ned sparkplugs 0 problems.

I'm pretty sure that modern Mazda's do do this, only not in the situation you're describing. They use it for their stop start system to save having to fit a beefier starter motor and what not, simply inject an extra dose of fuel and fire the spark plug to get the engine going again.

Ours has been pretty reliable, had some issues with odd stalling once which was cured with new plugs/wires/carbon cleaning, rear shocks just went recently.
