Spark plug Autolite or BRISK
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
Vehicle:
Jeep
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
About 6 weeks ago I finally changed the spark plugs. So I put somewhere near 180,000 miles on a set of Autolite spark plugs. Two of the spark plugs the center electrode was completely gone. I don't know how the fuck the engine ran and I certainly don't know how it did not throw a code , it still ran very smoothly even at idle.
Pros: ran smoothly even idle
Cons: electrode was completely gone
Vehicle:
Ford Ranger
Mileage: 289682 km
I've used Autolite plugs in the 2.0's I've owned for over 20 years now because I think they work the best of the ones I've tried with this engine.
Pros: work the best, long-term use
Vehicle:
Volkswagen Jetta
What plugs you're using may help. In my experience not all plugs are created equal. Brisk, for example, last maybe 5-10k miles before they're garbage. Whereas I can run NGKs for 15k+.
Pros: NGKs last longer
Cons: Brisk wears quickly
Mileage: 10000 km
Brisk silver er10s if you need 2 steps colder. I had the ngk plugs, but they wore down just as fast and are more expensive. Brisk silver are like 10 bucks
Pros: cheaper than NGK
Cons: wore down fast
Part number: ER10S
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
