Spark plug Autolite or OEM Audi
Ran Autolite Iridum XP XP3922 plugs in it and had zero issues at about half the price of the NGK plugs, and I had a mild tune.
Pros: zero issues, half price
Vehicle:
Chevrolet Cruze
Part number: XP3922
120k miles on my 2015 a3 with a stage 1 tune. I did timing belt, tensioner, and water pump around 100k miles. Costed me like $1k. Also did spark plugs and a new battery, which was another $600.
Vehicle:
Audi A3
Mileage: 120000 km
These are good plugs Autolite my mechanic recommended them to me good spark and seems like my truck is running smoothly and there a good price.
Pros: good spark, running smoothly
I am running platinum Autolite plugs in my 2.3 rwd and don't regret it
Pros: don't regret it
I replaced the spark plug with an Auto Lite spark plug. Engine light went away but still runs rough and misfire on acceleration.
Pros: Engine light went away
Cons: runs rough, misfire
Make sure if you purchase spark plugs that it is not Auto Light. They tend to mess your vehicle up more and not work well with Toyotas.
Cons: mess up vehicle, not work well
Don't use AutoLite plugs in this car, they are known to have issues.
Cons: known to have issues
Also, Autolite is extra terrible. I would have done anything else.
Cons: extra terrible
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
