Made a noticeable difference in throttle response. I put Bosch plugs in it a few months earlier and I just wasn't happy with them. I noticed the difference as soon as I installed these plugs. I would highly recommend these for your ecoboost Ford.

The plugs work great. Idles smoothly. I had an issue with spark blow by when the boost went over 20 pounds and so far I have had no issues with these colder plugs.

Great plugs. No miracle MPG increase or huge HP jump. Engine feels smooth and acceleration is steady. Had a stutter with some NGK plugs on hard acceleration, swapped to these plugs and no more stutter

Great plugs. Truck seems to run a lot smoother now, even pre tuned it feels so much better. One plug needed a minor gap adjustment but perfectly gapped besides that!

Customer Question what is the heat range number on these

Asked by: caleb coquat - 1/9/2024
Customer Answer Ford Performance does not list an actual heat range in any of their specs for the plug set other than mentioning they are 1 step colder than stock. With factory heat range being 6, that would make these plugs a range 5.

Customer Question Should I run these plugs in my tuned 2014 Tremor to help drive ability??

Asked by: Frank Corbett - 8/15/2022
Customer Answer That really depends on what issues you're running into. If you're having problems with spark blowout, then these plugs could help. However, if your truck is only tuned, you likely don't need colder spark plugs. Give us a call directly at 623-434-5277 or email us at [email protected] so we can get more specific about your issues.

Customer Question Do these plugs come pre gapped or no? Thanks

Asked by: Blake - 5/25/2022
Customer Answer These spark plugs should come pre-gapped at .031". However, it's a good idea to double-check before installation.

Customer Question Is a tune required to run these?

Asked by: Todd - 11/29/2021
Customer Answer A tune is required, but these plugs aren't really needed unless your vehicle is tuned. In general, the only reason you'd want to run colder spark plugs is if you're pushing out more boost, using water-methanol systems, using nitrous, using bigger turbos, or some combination thereof. In general, a truck running a stock tune would be fine with stock heat range plugs, though we do recommend using good iridiums.
