    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 2019 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.

        5 Top Rated Questions

        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.

            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 :)

            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.

            Failed after 4 months

            All I can say is to stick with oem or find another brand. Just sent my mustang to the shop and the spark plugs are melting. When it was first installed it worked great but then after 4 months with just short distance driving 12mi each way, my car is misfire get and then Christmas eve I got the check engine light. Have to go to the dealership to find out what was wrong and it's the spark plugs. They have to refresh my ecu and now they have to load back the Ford racing tune on it and it is costing me so much money for this spark plugs. I wish their is a claim for this for the cost. I did not purchase a performance spark plugs just to burn some money after 4 months of use. AM you need to address this with brisk at stop selling this plugs. These are junk!

            good product

            One of the first things alot of people told me was to replace the factory plugs with pre gapped plugs. Not a huge boost in power, but you can feel the difference. Obviously i need a tune to get the full potential but overall theyre great.

            Failed after less than 500 miles.

            This set of 4 didn't end up going well for me. The plug in the 3rd cylinder failed causing an engine misfire. I hadn't known what the issue was so I took it in to a Ford Service center. They told me it was the plug and because the plug was aftermarket and not Ford approved, they voided my labor warranty and I ended up paying 300 dollars for labor and new OEM plugs from Ford which I had had in the first place. I would not recommend these as they run a high risk of failing.

            1☆Fast Shipping - 1/4☆Faulty plug

            I normally use NGKs but decided to try Brisk since they get a lot of hype. Unfortunately one of the plugs was faulty When I pulled it the tip was covered by a loose part of the plug sliding down over it leading to misfires within 100 miles of installing them. Thankfully it didnt fall into the cylinder!!! Ended up gapping some NGKs from a local store and been fine since!

            I installed the brisk silver racing spark plugs after I broke my 2016 Mustang EcoBoost in. The stock plugs were already showing signs of wear. Now, my engine is running smoother and more aggressive, I highly recommend this product.

            Do This....

            I installed these plugs as part of a Cold Air, tune build. You really want to do this if you want the best response . They are gaped perfectly out of the box. They make for a smooth idle and great response when you step on it. These are a must have and at this price a good deal. When you see you stock plugs you be happy you added these. Happy I did this on my 2017 Ecoboost Mustang.
