Spark plug OEM Mazda or OEM Volkswagen

New plugs and coils went in and the misfire is gone. Sounds healthy too.

I did replace the spark plugs at 70k miles

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.

Just changed out the original plugs in my 2014 Ed30 GLi at 58K and totally agree with the other observations here. The idling has improved tremendously and the general over all performance of the car is back where it should be.

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.

Can't beat the 2.5 for hassle free reliability. Economy sucks, though. I have had my 130k mile 2.5 Rabbit since new and I have never averaged more than 25-26mpg in mixed driving, but on the other hand I haven't done much more than oil changes and spark plugs on it.

Look out for tensioner. Somewhat large maintenance at 40k intervals. (DSG fluid and filter, haldex fluid). Oil changes every 5-10k. Spark plugs every 40k a good ideal imo as well.

use oem plugs for the next 40k, its worth it, part number is 06H-905-601-A

I have the same problem with my recently acquired 2011 Sharan. Tried a suggestion of new spark plugs with no success.
