Spark plug Autolite or OEM Mazda
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
Ours has been pretty reliable, had some issues with odd stalling once which was cured with new plugs/wires/carbon cleaning, rear shocks just went recently.
Pros: cured stalling issues
Cons: rear shocks went recently
Vehicle:
Mazda 5
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
Autolite 4162's, I changed them out every 1000 miles.
Cons: short lifespan
Vehicle:
Volkswagen
Mileage: 1000 km
Part number: 4162
the autolites are bottom of the barrel, i've only used them once when i was young and dumb and ofc they busted while trying to repair and remove after.
Cons: busted while removing
Yeah, get rid of those: autolite is junk.
Cons: autolite is junk
Vehicle:
Volvo
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
