I also have a 2014 hemi, had these plugs in for 20K miles they look great.
Most of the time, that is the best dynamometer to use. I looked into the factory stats/specs on my new Warlock, and it said 0-60 (MPH) times were about 6.5 seconds. I independently confirmed this, sitting at a stop light, waited until it turned green, then stomped on the gas. Had to try it again as it spun the back tires, so into 4WD it went, and on the second/actual test, it did roughly that time. Put a new K&N air filter in it, no other changes, and got it down to about 6 seconds flat. All using that "seat of the pants" style dynamometer, less expensive to maintain, and usually a lot easier to calibrate.Unless you have dynamometer printouts that are not over corrected for SI or Pa pressure you’re just measuring performance improvements by the seat of your pants.
Plug replacement on Ram hemi not as bad,in my experience,as some others also. Some folks lack the skills and mindset I suppose.I just put in Automate Double Platinum, that was all I could get, they were about $5 a piece. The NGK Iridiums were $13.99 ea and backordered. Wasn't a bad experience, I have a nice toolset so the different sized extensions and the swivel attachments worked well. Honestly, the rear three spark plugs on any front wheel drive V6 engine (Vulcan 3.0L, GM 3.1 and 3.8L) I have changed were far more challenging than the ones under the brake booster on the Ram.
90k mi and the truck runs like new. I didn't realize how degraded the power had become. That's the longest I've ever gone on a set of plugs.
