Spark plug Autolite or BRISK
Brisk plugs off Parker performances page. The brisks hold there gap and seem to really last
Pros: hold gap, really last
I put Autolite Iridium plugs in my '06 N52 20k miles ago because of a crazy sale/rebate. It runs as smooth as a new one.
Pros: runs smooth as new
Vehicle:
BMW
Mileage: 32186 km
You're on the right track- replace those worn out plugs. Pre-detonation started on my '18 at 30k. Increasing octane rating to 93 worked up to 58k miles. $50 for a new set of [Autolite Iridium XP5363](https://www.amazon.com/dp/B078KWTCF2?ref=ppx_pop_mob_ap_share) resolved this problem.
Pros: resolved pre-detonation problem
Vehicle:
Ford
Mileage: 30000 km
Part number: XP5363
I've ran Autolites on my racecar that runs in the 7's for 20+ years with no problem. They are the only thing I trust at the moment
Pros: trustworthy, no problems
I'm running brisk One step colder plugs at 0.024 Gap with my eqt stg 2 tune. they are amazing
Pros: amazing
I'm getting some knocks in all cylinders in the first revision, more than I did with the Cobb OTS map and stock spark plugs. Hopefully it gets sorted out in the next couple of revisions and if not, I'll have to check the spark plug gaps or maybe re-run with the Cobb OTS and see if the knocks are due to the tune or spark plugs.
Overall, the power delivery is great.
Pros: great power delivery
Cons: getting some knocks
Don't even think the Autolite or Bosch last as long as Denso/NGK spark plugs.
Cons: do not last long
Vehicle:
Toyota Camry
autolites were fine 100 years ago
now stick with NGK or whatever OEM was. its not worth it to be fudging around and what little your gonna save may be burned up in less MPG using some other plug.
Cons: less MPG
I've had nothing but bad luck with Autolite brand.
Cons: bad luck
I have a poor running Audi in the shop now. While it needs more than plugs, it has autolites.
Cons: poor running
Vehicle:
Audi
