        Did the trick.

        Purchased these to replace my stock spark plugs. Had some misfiring going up hill or under a load. I replace the as all the plugs and complimented them with MSD coils. Runs like new.

        Works just as I needed it to

        Engine was idling a little rough, swapped out the stock spark plugs with these and new coil overs and noticed an immediate improvement

        5 2015 XLT - JoshS Installation Time: Less than 1 Hour

        Shockingly Nice.

        Bought these for my 2015 Ford 3.5L. The install was very simple. Plenty of "How-To's" on the almighty YouTube. Takes a little bit of time to get these in but only due to process itself. I'd say an hour or more if you have not done it before. I have 64,000-ish miles on my truck. With no issues. I heard the plugs were more of a 2011-2014 issue. I did not need to change these out but I am going to tune my truck so I bout these as a preventative measure. Even though the truck is not tuned yet, my 2015 is running just fine, very smooth as always, NO CEL, no loss in MPG or anything. I'd say grab them if you need them or if you plan on tuning, can't go wrong either way BUT I am speaking for a 2015 model.

        Great for tuned trucks

        My truck is tuned and I felt the stock plugs weren’t cutting it. Really smoothed out the idle and can tell a significant difference in performance. MPG is better when you keep your foot out of it. Very pleased and definitely recommend. Install is a breeze.

        Great Upgrade for Ignition

        After installing a set of these plugs my Ecoboost F-150 idles smoother and has faster acceleration. All of the plugs were gapped to .028 out of the box, no variation

      Would these be recommended for stock 3.5L Ecoboost engine with AFE MAGNUM FORCE STAGE-2 DUAL 3-1/2" COLD AIR INTAKE SYSTEM W/PRO 5R and AFE ATLAS 4" Aluminized Steel Cat-Back Exhaust System?

      • No, These would be best used with boosted applications.

      I am putting in the accel supercoils on my 2015 Ford 3.5 Ecoboost engine. Are these plugs a good choice for me? I have not done any other upgrades nor do I plan on it. Just looking for a good plug.

      So looking at the questions i have some concerns. Could i install this product on my 2013 platinum 3.5L ecoboost twin turbo. I have not done any upgrades on the engine. Everything is stock.

      What could happen to you engine if you use these on a stock 3.5l Ecoboost?

      would you recommend a granitelli or msd coil pack with these plugs? Have a 2013 f150 ecoboost 3.5L with dual cold air intakes, catted down pipes, 4 inch exhaust, cold side pipe on inner cooler, BBK throttle body, SCT tunes

      • Both the Granatelli or MSD coil pack will work well with the Ford Performance Cold Spark Plugs.
