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.

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

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.

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.

Just replaced all my spark plugs that were in for 83k miles. Autolites were in and replaced with Denso twin-tip.

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.

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.

Probably going to need to pull them again within a couple years. Autolites are the absolute worst sparkplugs.

If you need new spark plugs... Don't use Autolite.

Autolite plugs are junk. You’re better off leaving those 200k OEM plugs in it.
