Spark plug Autolite or BRISK
I've ran these for a few years stage 2 e85, with absolutely no issue at all. The last year and a half I've been running a bigger turbo, powermax 2260 and have had zero issues
Pros: no issues at all
Been running them for the last year on EQT stg 1 91 and e30 with no issue.
Pros: no issue
Check out Brisk Silver Racing (listed as an option by EQT). You’d have to replace them more often vs iridium, but they are super inexpensive and more performance oriented (conductivity).
Pros: inexpensive, performance oriented
Cons: replace them more often
These are good plugs Autolite my mechanic recommended them to me good spark and seems like my truck is running smoothly and there a good price.
Pros: good spark, running smoothly
after changing the spark plug for another autolite it stopped misfiring its still a little rough so I fear it may comeback so I just ordered some NGK plugs.
Pros: stopped misfiring
Cons: still a little rough
Vehicle:
Volkswagen
I have used Rs7 plugs (meh), the APR recommended NGK plugs (rough idle, gapped correctly), and the Brisk ER12S. I'm on my second set of the Brisk, and plan to keep using them.
Pros: cheap enough
Cons: change them at 10k
Vehicle:
Volkswagen Golf
Mileage: 10000 km
it was the Autolite spark plugs. Had car towed to my mechanic. They replaced with spec NGK and the car is running fine.
Pros: car is running fine
Cons: car misfires
Vehicle:
Mazda
I bought Autolite spark plugs but after researching I should of bought NGK. Right after replacing them when I accelerate my car jerks or misfires when driving. When at an idle I felt my car jerking.
Cons: car jerks or misfires
Vehicle:
Nissan Altima
Put autolites in my Durango, ran like junk nd put NGK in and better.
Pros: NGK is better
Cons: Autolite ran like junk
Vehicle:
Dodge Durango
Also I would stay away from Brisk ER12 spark plugs since they require higher change intervals (And risk of damaging coil packs) @ 3-5K miles as opposed to NGK R7437-8 or NGK R7438-8 @ 10-15K miles.
Cons: higher change intervals, risk damaging coil packs
