Spark plug BRISK or Denso

Ive been using the Brisk USA Premium Racing Spark Plug 14mm... yeah I get it they are kinda expensive when it comes to spark plugs at little over 13 dollars a piece but trust me they are worth it, ive never had good luck with any of the spark plugs listed for the 2.5l, specially not with what I've done to it, iridium plugs, platinum, copper, Nicole, even ruthenium plugs.... but these Brisk plugs are killers, ive never had my car run this well before, even my throttle response is better and the heat range is correct as well..

Get the oem denso ones. There is nothing better than oem for that kind of thing.

This is what a 202k mile spark plug looks like on an 2013 Lexus gs350 daily driver. Pretty impressed with it overall. All 6 plugs look exactly like this.

For spark plugs, denso or bust

I got mine from ECS: drop-in replacement and no issues even with my Burger unit on map 2.

I've been running Denso (5346) IKH24 Iridium gapped .024 on APR stg1 for 48k miles and most recently on stg 2 with no issues.

I currently run the Brisk er12s and have been happy with them...I'm mpi running full e85 and the car responds well. It's also what my tuner recommended.

I got a set of APR coils and Brisk Silver Racing ER12s plugs for around 200

No discernible difference to me, positive or negative. But since I am running APR stage 1, I followed APR's recommendation.

The original dealership where I bought the van installed Denso spark plugs part # SXU22HCR11S which were supposed to have a gap of 0.044 but they all had either 0.039 or 0.040. Apparently no one checked the gap before putting them in.
