Your engine’s power starts with a spark, literally. ⚡️ Old, worn-out spark plugs can cause misfires, poor fuel economy, and sluggish performance. Whether you’re daily driving or chasing lap times, fresh plugs keep your ignition crisp and your engine running smooth. That’s why we trusted Bosch in our Upgrade or Unload B7 episode. They have OEM pedigree, precision engineering, and built to meet the demands of European performance. Time for a tune-up? ECS has you covered with the right Bosch plugs for your build and if you snag any Bosch products between now & 5/31 you’ll get double the entries into our 8Y RS3 Sweepstakes! No purchase necessary.
