Spark plug Denso or OEM Volkswagen

IKH 24 plugs with stock coils work just fine. No cutout, rough idle or misfire.

Replaced stock with denso ihk24.

I did replace the spark plugs at 70k miles

denso ik22 works also, also an iridium tipped plug

I bought a box of denso.

Everyone has been praising (fleet vehicles).

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.

Im with the Densos already and the spool and throttle response is so much better. Even with gap 0.075mm they are much better.

I have the denso ikh24 and no problems for me.

Just an update for you and a PSA: CHECK YOUR SPARK PLUG GAP ON NEW PLUGS. I too trusted that the iridium plugs that I just bought should've been pre-gapped, but I noticed immediately after a tune-up my gas mileage went to piss. Popped the plugs back out and sure enough each one was well over 1mm .

The original dealership where I bought the van installed Denso spark plugs part # SXU22HCR11S which were supposed to have a gap of 0.044 but they all had either 0.039 or 0.040. Apparently no one checked the gap before putting them in.
