vs
Spark plug Autolite or OEM Subaru
Reviews
If you care more about performance, or cheaper cost, get the autolite a103, or ar103. Those will give you the best performance, but they only last like 10k. But they’re also dirt cheap.
Pros: best performance, dirt cheap
Cons: short lifespan
Mileage: 10000 km
Part number: A103
im at 95k with the original plugs. no issues
Pros: no issues, lasted 95k miles
Mileage: 152887 km
I waited till like 100k to do my spark plugs on my 2013 Crosstrek, they were still good just not as efficient
Pros: lasted 100k miles, still good
Cons: less efficient at high mileage
Vehicle:
Subaru
Mileage: 160934 km
Just traded in my 2015 Forester with 219,000 miles and the original spark plugs.
Pros: lasted 219,000 miles
Vehicle:
Subaru Forester
Mileage: 352445 km
after changing the spark plug for another autolite it stopped misfiring its still a little rough so I fear it may comeback so I just ordered some NGK plugs.
Pros: stopped misfiring
Cons: still a little rough
Vehicle:
Volkswagen
Local mechanic used an Autolite plug, not Honda-recommended NGK. Misfires stopped for a month, then happened twice more. I have since discovered this brand does not run well in a Honda engine.
Pros: misfires stopped for a month
Cons: misfires returned, does not run well
Vehicle:
Honda Pilot
I changed my plugs to autolite because I had never heard anything bad about them. I replaced them after 3 weeks due to misfires, put another set of autolites in and it ran fine for 2 weeks. Started misfiring again and swapped in a set of NGK's, no problems since.
Pros: ran fine for weeks
Cons: caused misfires
I would never install Autolite on any car, definitely not the WRX.
Cons: never install
Vehicle:
Subaru
Out of all my years replacing spark plugs. The only times I got bad spark plugs that misfired right away is the one time I ordered a fake set thru ebay(my fault for not doing my due diligence) and a set of brand new auto lites from autozone.
Cons: spark plugs misfired
I purchased some Autolite XP Iridium spark plugs earlier this month and immediately installed them. Within a mile of driving, the car started shaking violently and the check engine light came on. I immediately turned around and reinstalled the old plugs and the problems went away.
Cons: car started shaking violently
