Reviews of OEM Volkswagen spark plug

I’ve done an oil change as well as swapping the spark plugs and coils for brand new ones. The roughness persists!

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.

Today I replaced the spark plugs with new ones PFR7S8EG VW genuine. With new plugs car runs better, but idle still wasn't good enough.

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

My CC is 2 years old and I have accumulated 65k miles. I changed the plugs at 60k. They looked pretty toastyso I am glad I did.

Plugs 97K on my 2010 original ones...working great (lots of highway miles). I'll be changing them at 100K.

For the misfiring check your spark plugs it can be that simple... i got a mkiv golf too.
