vs
Spark plug Autolite or Denso
im using the denso 1k22 great plugs for ko4
Pros: great plugs
Part number: 1K22
Now I'm running autolites one range colder than stock at .028 and they run great...
Pros: run great
Last time I tried the 3922s and I was pleasently surprised with how smooth the car runs. I haven't had a misfire code since I changed over.
Pros: smooth car runs
Cons: no misfire code
Vehicle:
Volkswagen
Also I'm using the 3922's and love them. They went a long way in solving my timing pull probs w/ my ATP Stg3.
Pros: solving timing pull probs
Part number: 3922
It was time to change the plugs so I went for one range colder (from Autolite 3923 to 3922). Before I installed these plugs, the power would drop off dramatically above 5500 in 3rd, 4th, and 5th. Now it is a much more progressive decline. The car actually maintains that pushed back in the seat feeling in the upper revs now.
Pros: progressive power decline
Cons: power drop off dramatically
Part number: 3922
The cheapo Autolite 3923 works very, very well. Works well with chipped and K04 cars also.
Pros: works very well, good for modified cars
Part number: 3923
i put in some 3922s and i can hear it misfire when its idling, but it seems fine when im giving it gas.
Pros: fine when accelerating
Cons: misfire at idle
Part number: 3922
I took a peak at mine the other week and the gap was HUGE so gapped them down to .035 and now cold starts are ROUGH. The pugs in there suck, anyway - old autlites.
Cons: rough cold starts, poor performance
After changing the plugs from OEM's to Autolite 3923's, the coil packs started popping up. I've read that the Autolites are smaller than the OEM's, so they don't hold on as tight...and then somebody else said this is bogus and they're both the same. Whatever the reason, the coil packs on my car do not like the Autolites.
Cons: coil packs started popping
Just installed my autolites 3922 (one range colder than stock 3923) they were gapped to 0.025" with this gap I'm having some problems on hot startups, colds ones are ok. I'll regap them tomorrow and see if it gets better, maybe I'm having some loss in performace as well due the small gap....
Pros: cold startups ok
Cons: problems on hot startups, potential performance loss
Part number: 3922
