vs
Spark plug Autolite or BERU
I have autolite xp in the van. $100 for 6 ngk, $90 for denso with a van with 250k miles. Everyone says there crap, but it runs great.
Pros: runs great
Cons: everyone says there crap
Mileage: 250000 km
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 ran Beru RS7 plus which are one step colder when I tuned stage 1 and they didn't last at all. Might have been under 10,000 miles. Recently went with NGK plus that APR reccomends for stage 2 and so far so good. No misfires since.
Pros: no misfires
Cons: didn't last
Mileage: 10000 km
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
I would never install Autolite on any car, definitely not the WRX.
Cons: never install
Vehicle:
Subaru
Out of all my years replacing spark plugs. The only times I got bad spark plugs that misfired right away is the one time I ordered a fake set thru ebay(my fault for not doing my due diligence) and a set of brand new auto lites from autozone.
Cons: spark plugs misfired
I purchased some Autolite XP Iridium spark plugs earlier this month and immediately installed them. Within a mile of driving, the car started shaking violently and the check engine light came on. I immediately turned around and reinstalled the old plugs and the problems went away.
Cons: car started shaking violently
