Spark plug Autolite or OEM Mazda
I used them in my 2007 Tacoma with no problems. Left them in for several years.
Pros: no problems
Vehicle:
Toyota
I put autolite's in my 2010 V6 and they've been perfectly fine.
Pros: perfectly fine
Vehicle:
Ford
I find that chevies and dodges like autolite or delcos, fords i run motorcraft only, japanese stuff gets ngk's or bosch.
Note that decent spark plugs are hella expensive, but worth it due to lasting a lot longer than cheap $4 Autolite's.
Pros: long lasting
Cons: hella expensive

I bought Autolite spark plugs but after researching I should of bought NGK. Right after replacing them when I accelerate my car jerks or misfires when driving. When at an idle I felt my car jerking.

Put autolites in my Durango, ran like junk nd put NGK in and better.
Pros: NGK is better
Cons: Autolite ran like junk

With almost every car, using OEM plugs is the way to go. The one brand to ALWAYS avoid is Autolite. They are extremely poor quality and I have never seen them work long enough to justify the cost saving.
Pros: OEM plugs are best
Cons: poor quality, short life
Autolite plugs are bad.
Cons: bad quality
Part number: FR7HE02
