Spark plug Champion or BRISK

I just did mine not too long ago, replaced with Brisk ER12S. Didn’t need a coil puller tool, just had to be careful getting them out. Warming up the engine is helpful too. Otherwise an easy job.

You can get the champion version of the RS7 plugs for less than $20 a plug and they’re working great on my car!

These were actually alright spark plugs. The ceramic is a lot tougher than normal ceramic, and the electrode is larger. They were marketed as 'truck plugs', but they're really good in old tractors and farm equipment. They last forever.

For spark, I wasn't sure I had the right plugs so I went with the OEM Champion plugs that were recommended in the Bentley. I checked for spark, no issues there.

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..

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

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 once had to use 99 cent Champion plugs in my car for a few months when I was flat broke. They worked fine but didn't last long.

Champion plugs are barely adequate for a lawnmower...

Champions are crap.
