Spark plug Autolite or BRISK
I switched to brisk just because of the high amount of ngk knock offs and they are supposed to last a bit longer and or have less wear than the ngk I'm a step colder rr4ys they have been great.
Pros: great, supposed to last longer
Cons: high amount of knock offs
I have a 3.5 ecoboost. All 6 of my Ford plugs failed because of cracks. I replaced them with AutoLite iridium XP5863. They are all still going strong after over 50k miles.\n\nThe Ford plugs failed with a cylinder misfire error code. The engine would also bog down under havy accelaration
Pros: still going strong
Cons: cracks, cylinder misfire
Mileage: 80467 km
Part number: XP5863
You get a better performance if you install a booster plug, DNA air filter and Brisk spark plugs. Great torque from 2000 rpm as a result.
Pros: great torque from 2000rpm
Vehicle:
BMW
I just run oem plugs gapped to . 024 as recommended by eqt who I'm tuned by. No knock, I had brisks and Ruths before, my car didn't really like brisks and Ruths just made it misfire closer to the 5k change out.
Pros: no knock
Cons: caused misfire
Mileage: 5000 km
Just replaced all my spark plugs that were in for 83k miles. Autolites were in and replaced with Denso twin-tip.
Mileage: 133575 km
Autolite are garbage plugs. Get denso or ngk plugs and gap them accordingly before installation. You can see signs of blow-by at the porcelain.
Cons: garbage plugs, signs of blow-by
I agree with everyone saying NGK but I would also like to recommend you do not buy an autolite if you need a substitute, they have horrible quality control.
Cons: horrible quality control
Probably going to need to pull them again within a couple years. Autolites are the absolute worst sparkplugs.
Cons: absolute worst sparkplugs
If you need new spark plugs... Don't use Autolite.
Cons: Don't use Autolite
Autolite plugs are junk. You’re better off leaving those 200k OEM plugs in it.
Cons: Autolite plugs are junk
Mileage: 200000 km
