Spark plug OEM Subaru or OEM Volkswagen

Since then I have take good care of it, replaced the brakes on schedule in August 2020 and then in August 2021 new spark plugs.

And also removed and cleaned my spark plugs. All these collectively seemed to have a great impact on the engine\u2019s performance! The engine runs much smoother and feels a lot more sporty!

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

My 2002 had a similar issue. In my case it was the spark plugs, $250 fix.

I did replace the spark plugs at 70k miles

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.

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.

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

a spark plug job on an STI can be a 6+ hour job :thumbdown:
