vs
Spark plug Autolite or OEM Audi
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
If its just painted like some cheap plugs such as some autolites then yes its needed.
Pros: needed for painted plugs
Cons: not needed if coated
So here is my experience with gaps on this engine. The wife 09 Passat was misfiring so I decide to replace the plugs. I buy Autolite double platinums which were gapped huge. Turns out the 0.032 gap was not correct after all and it should have been 0.028. Big difference, this baby flies again (GIAC tune).
Pros: baby flies again
Cons: misfiring, gapped huge
Vehicle:
Volkswagen Passat
Autolite 4162's, I changed them out every 1000 miles.
Cons: short lifespan
Vehicle:
Volkswagen
Mileage: 1000 km
Part number: 4162
My dad just returned a set of autolites. I installed them and had immediate misfire.
Pros: easy to install
Cons: immediate misfire
Once we got a good local supplier for Motorcraft plugs a few years ago we almost never install Autolite.
Pros: good local supplier
Cons: almost never install
There seems to have been quality issues with those for quite a while. I couldn't count how many times we removed fairly new Autolite spark plugs and replaced them with a better brand to fix a misfire.
Pros: fixes misfire
Cons: quality issues
I wouldn’t put autolite plugs even in my lawnmower. NGK or Denso only.
Do not get Autolite, I've seen them cause trouble and issues in Honda engines.
Cons: cause trouble, issues
Vehicle:
Honda
