vs
Spark plug Autolite or Denso
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
I found that it had Autolite Iridum spark plugs. They didn’t look bad and were gapped appropriately but I replaced them anyway with the recommended NGK spark plugs. Car has ran perfectly since then with no misfires or stuttering.
Pros: car ran perfectly
Cons: misfires and stuttering
Vehicle:
Saab
I now have the new plugs which are autolite gapped at .027 as it is suggested by autolite and also in the Bentley book.
The truck is currently using Autolite XP5245 iridiums. Normally I would go with something from NGK but I figured if the Autolites were a decent price I would get them and they would probably last the life of the truck
Pros: decent price
Part number: XP5245
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
Currently just swapped to Denso's IK20 like 2 months ago. They run pretty good. But now its mid summer over here and the car runs a little bit underpowered at those high temps.
Pros: run pretty good
Cons: underpowered at high temps
Vehicle:
Audi A3
Part number: IK20
I work on euro cars. If I'm diagnosing an issue that even has me think misfire and it has autolites, I'm done until they're in the trash can and OE is installed.
Cons: trash can
My experience with auto lite has been complete trash, and their review ratings are always great. Anybody else have problems with auto lite plugs?
Cons: complete trash
I had EPC light/limp mode and P303 as well about a month ago on my '12 GLI (APR Stage 1+) at 102K miles that recently had a walnut blast and new Denso plugs at around 101K miles. Swapped coil packs as well and still P303 with EPC light/limp mode.
Cons: catastrophic failure
Vehicle:
Volkswagen
Mileage: 101000 km
