      Description

      High Powered Performance. Don't replace your EcoBoost Mustangs old spark plugs, upgrade them!
      Brisk Silver Racing Spark Plugs are the perfect performance upgrade for EcoBoost Mustangs that have lost power due to fouled or damaged plugs. It is highly recommended to change your old spark plugs every 30,000 to 45,000 miles as part of your Mustangs routine maintenance.

      Superior Design and Materials. Brisk Silver Racing spark plugs feature a high dielectric strength insulator and use a 1.5mm fine wire silver center electrode for its excellent electrical and thermal conductivity which in turn produces a more powerful spark. The tapered ground strap design allows for superior ignitability on hard to ignite fuels minimizing the chance fouling.

      Application. This set of four (4) Brisk Silver Racing Spark Plugs are specifically designed for the 2015 to 2020 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-Cylinder engine.

      Technical Note. These Spark Plugs are ideal to be used on a Non-Modified/Stock EcoBoost Mustang. If your planning on modifying the vehicle, especially with a tune, it would be best to get a non-projected spark plug like Brisk's part# RR14S or a colder heat range spark plug like Brisk's part# RR12YS.

        So far there awesome

        Got these installed less then a week before I took it to the tracks, too soon to really see a difference, only about 400 miles or less, figured if I was going to have a issue it would be at the tracks, they have held up during the stress making 6 passes

        Decent Buy, did not notice much change.

        Value for money I guess. Easy installation, marginal notice in gains.

        Best plugs you can buy!

        These already come with a lower gap out of the factory which allows you to run stupid tight like .022 - .026 on boosted applications and the strap remains parallel, not over ached. They last twice as long as NGK of the same style. For the money this plug can't be beat in high hp applications :)

        Lasted 3 months

        I bought these in July and it's now October and my car started misfiring. I had to replace these already. Not worth $40.

        3 2017 EcoBoost - Jnovuse Installation Time: Less than 1 Hour

        3 Star only for Brisk's Customer service.

        I had two plugs fail within 1500 miles. The first time, the ceramic sleeve was wobling back and forth, It happened when I was just normal street driving on a Stock Ecoboost. I figured maybe it just was a bad plug, so I contacted Brisk, they sent me a replacement and a t-shirt within a few weeks. Then the second one failed halfway through a 65 mile drive in the desert. I put the OEM plugs back in, and haven't had an issue yet. Brisk has great customer service, but these plugs are not worth it or great for our cars.

        Nice plugs

        After doing some research, I decided that Brisk was the way to go. I used nickel anti seize and a light dab of dielectric grease. I replaced the stock ignition coils with Granatelli Street coils. Overall throttle response seems better but I'm not sure if it's just because I put new plugs in or if it's the plug/coil choice. I'm happy though. Time will tell. It's been 4k miles and I have noticed improved gas mileage as long as I don't hog on it.

      Can you give me a comparison between the NGK Iridium spark plug vs that of the Brisk Silver Racing Spark Plugs as to why the Brisk is better over the NGK Iridium?

      • There really is no comparison, they are going to be extremely similar. The Brisk are usually that upgraded replacement over stock, whereas the NGK are usually meant for race applications. You will not really notice a difference going with one or the other.
