denso ik22 works also, also an iridium tipped plug
Pros: works also
Part number: IK22
I bought a box of denso.
Everyone has been praising (fleet vehicles).
Pros: praised by many
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.
Pros: idling improved tremendously
Vehicle:
Volkswagen
Mileage: 93342 km
Im with the Densos already and the spool and throttle response is so much better. Even with gap 0.075mm they are much better.
Pros: much better spool, much better throttle response
Part number: IK22
I have the denso ikh24 and no problems for me.
Pros: no problems
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 .
Cons: gas mileage went down
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.
Cons: incorrect gap, poor quality control
Part number: SXU22HCR11S
