Spark plug Autolite or BRISK

Heat Exchanger, also Brisk racing spark plugs I gapped mine to 0.026”.

Some people swear by the Brisk plugs, but I'd spend that coil money on either the Denso or NGK plugs that EQT recommends.

I would also like to leave a comment here about having success with an autolite AR52 plug. Same exact thread size and identical reach as the OEM torch plug.

Autolite or Brisk plugs with stock gap.

I have a 05 with Edelbrock SC, 11 pounds of boost, and E85.

Call me stingy, but I have an issue paying $40 for 1 spark plug. Especially when I can run a set of Brisk Racing Plugs for $60.

I was running stage 2 apr with rs7 brisk plugs, had misfires on cold start. Did carbon cleaning myself, misfire kept happening. Spark plugs kept getting lose even after torquing. Switched to Oem spark plugs and no more misfires.

I would never install Autolite on any car, definitely not the WRX.

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.

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.

Autolite are pure trash maybe suitable for a lawn mower if you like breaking plugs off in heads
