I have found the JB4 to make much more of a difference than the Ford Tune and recommend doing it first.

I know this an old thread but just wanted to share if anyone was interested. The equivalent Ruthenium plug to the Iridium IX 6510 plug is NGK 95605 LTR7BHX Ruthenium HX Plug

I went with the colder NKG plugs and just swapped them back to the factory plugs after having days worth of misfires. Not sure why the issue. Glad I did not throw the old ones away.

I’ve been just fine with the supplied one step colder NGK plugs offered by Panda motorsport. Works well with the supplied Panda power module.

I bought the plugs awhile back and was planning to install them. Glad I read through this thread entirely. I’ll definitely be holding on to my OEM plugs just in case. I have the FP tune and a Cobb CAI box and filter. I’m planning to install the Mishimoto High Mount inner cooler. Curious about the JB4 Piggy back. How Is the installation process. I had a Ford Performance tech do my procal install.

Ya know - I just thought if this. I had the colder plugs in my 2021 from the Panda kit since they first released it in 22. I had to get my catalytic converter replaced twice under warranty. Once at around 35k and again at 50k. I wonder if it’s related. Keeping the OEM installed on my 2025 for sure.
