        1 Top Rated Question

        Will these work for my 03 Saleen? I do not the specs of the current ICs for Saleen, if any. But if these have a higher output, would there be any other ignition parts that would need to be matched up with these particular ICs? (Spark plugs, ...)? Thank you, Jay Jensen PS you need put Salen and Roush as selections for the Mustang type. Selecting "other" just doesn't sound right. :)

        • Should work, get some iridium NGK boys and you should be in good shape.

            Work as Described

            Didn’t cure the issue I am having but I can feel the difference of more response, also a little better mileage.

            best bang for my buck

            The Sultans of Spark 40k advertised spark is 2x that of stock. Plug n play is so easy. ran with one step colder plugs as iam running 17-23lb.(depending on pully and tune) boost from whipple ford racing supercharger. Fired right up didn't miss a lick after 14 yrs on stock coils n plugs. ready to shred my MT drag radials.

            Fit great!

            I have trusted Performance Distributors since my Fox days. I know there is a lot of discussion around aftermarket coils not making a difference. I wanted to replace my originals, and trust that these are at least as good if not better than the replacement coils out there. I can't quantify any gains or losses, but fit great and my original test drive seemed like they were doing their job with the larger 0.065" plug gap as recommended.

            Good Replacement vs Stock

            These ignition coils smoothed out my rough idle, and increased the throttle response of my Mach 1. Had a misfire, and decided to give these shot. I replaced the coils and plugs at the same time, and my idle is now at 700 rpm and is much smoother, without breaking up in fourth and fifth gear like it was. Throttle response is better. Horsepower gain, however, is negligible. I do like these coils, and they did what I needed them to do.

            this product does increase ignition performance

            My cobra was running fine to start with. I wanted to add a multiple spark discharge ignition, but apparently that is unheard or for an 01 cobra motor. I installed the coils and regapped my standard copper plugs as instructed to .065". Car started right up and idled smoother than it did before. Car seems to have a smoother and better sounding midrange when under full throttle pulls than it did before. The next morning when i tried to start the car, it failed to start for the first time ever. I smelled gas and it seemed to be firing on only one cylinder. I waited an hour but same symptoms persisted. Pulled the spark plugs to investigate and 7 of 8 were wet with gas. I believe that the extra compression ratio of the factory 01 N/A cobra engine snd the increase in spark plug gap is a poor match for my application. I purchased new IX plugs and made sure the gap was correct for my application at 0.055". My cobra started right up and has been running perfect since. Please revise instructions to not recommend increasing the gap for 01 cobra applications.

            Not a bad add on if you have a little extra cash

            Bought these over the MSDs because they were on sale. Gas mileage improved a little as did throttle response. No complaints from me about this product.

            Fixed misfires

            These replaced my stock motorcraft coil packs, and they did the trick, I was misfiring because moisture conditions were effecting the engine after cleaning out the spark plug ports and everything out I swapped these in and got noticeably stabilized idle and generally the car runs smoother. These are worth it. MODS: BBK CAI, Flowmaster Hpipe,

            Sultans of Spark

            These COPs really helped my cobra out with hesitation. It turned out I had some old stock coil sons, I definitely recommend the higher voltage like these. Super easy to install also, if you have a wrench and have the ability to plug a cord into an can install in under a half hour. Most time consuming part was taking off the air intake. As far as gas mileage goes, I'm still on my first full tank since installation. I'm just above half a tank now and have about 20-30 more miles than I used to .
