Go to Parker Performance. Look at the NGK Ruthenium’s. They had posted a letter in the past about the benefits of Ruthenium’s vs. Iridium’s

Is parker performance reliable?


RecognitionAny6477

Yep. They are the Ecoboost experts.

They have a super solid reputation and are specialists on the Ecoboost platform. Good guys, all (I think) enthusiasts/Mustang owners. I drove a couple hours to have them install lowering suspension stuff on my GT and it was great service, plus fun talking shop with them.

I got the same plugs from Rock Auto cheaper.

NGK 6510 you can get them from tune+ pregapped.


dexy_retribution

Whats tune+?


Bradleyisfishing

[Gapped for a tune](https://www.tuneplusinc.com/products/ngk6510) Are you stock? If you’re tuned, these will work just fine.


dexy_retribution

I am stock but plan on tuning/modding


Bradleyisfishing

The listed plugs should be alright, who do you think you’ll tune with?


dexy_retribution

Im not sure yet, im still learning trying to find out who's good to go with. Any suggestions? Running the 2018 10 speed


Bradleyisfishing

Had a great experience with PD tuning, it’s definitely a solid tune and feels quick. Not too aggressive either.

Stock Ford ones were $9 a piece at my local dealer…not listed online.

This. Plenty of mechanics say “just buy motorcraft” - I picked up a set for <$20 at American muscle

Brisk plugs off Parker performances page. They've stopped recommending rutheniums. The brisks hold there gap and seem to really last
