Spark plug Autolite or BERU
Ive ran Beru ultra copper core for a couple months now and they are one step colder. I honestly dont even check gap on them and my shit runs smooth.
Pros: runs smooth
Almost any spark plug is better than the Torch it comes with. The recomended is the NGK BP7ES, but is not made any more, many use the BPR7ES without issue, which is a resistor plug, but the manual specifically says to not use a resistor plug. I am using an [Autolite AR52 plug](https://a.co/d/7Z3keDh), it crosses with the stock Torch and NGK BP7ES and is a non-resistor plug. Many people hate Autolite plugs, but I have been using them for years in other vehicles and never had an issue, and so far it is working just fine in my 11500.
Pros: working just fine
Cons: many people hate
Part number: AR52
Since spark plugs don’t cost that much I played around with a few. My 05 TJ like the Autolite APP985 the best. Hated the NGK ZF5RN the most.
Pros: Autolite APP985 the best
Cons: Hated the NGK ZF5RN

Cylinder Misfires started on #2, progressed to all, replaced all spark plugs and all spark plug wires. Cylinder misfires now gone. Spark plugs and spark plug wires all in bad condition
Pros: cylinder misfires gone
Cons: spark plugs in bad condition
If it didn't misfire until you put plugs in it I would suspect the plugs are the cause.
Cons: misfire after plugs
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
Most Asian brands are pretty picky about spark plugs. You put Autolites in a 70s malaise-era Ford - not in a modern, sophisticated, computer controlled, turbocharged Honda.
Cons: picky about spark plugs
Vehicle:
Honda
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
