yep, did it.
I hope we will see a before and after dyno for these....

Dyno Curves AFTER:
I have them in the car currently. I'm not sold that they are worth the added costs though.
I previously compared them to e3 spark plugs. Placebo effect
PSPE® (projected square platinum electrode) provides the best ignitability and service life for high-heat engines. This NGK-patented design is recommended for turbo and supercharged engines.
HIGH IGNITABILITY FOR BETTER COLD STARTS.
BETTER DURABILITY AT HIGH TEMPERATURES
MORE STABLE UNDER PRESSURE
So yeah.... Easier starts... More durability and that's all I was going for. Being this is my daily driver.
Let's see what ya got.
I'll put them to the test at 160miles per day with mostly highway cruising at 80mph.
Been running these ngk spark plugs almost all year. Had a few tune revisions for intercooler and hpfp. Brad didnt see a difference in the spark plugs on the graphs with msd coils. Reliability and longtivity, who knows i replace spark plugs at 10k miles regardless of what vehicle or type. 10k miles for me is probably way more than a year as its a "pleasure" car. And ive only put 2k miles on the car since this time last year.
I also went with the LTR7BHX, 1 stage colder. Not sure if thats the same part number as you put in or not.
I don't plan on changing mine again..... Unless something happens to cause it to be necessary. In older cars I used to notice a difference in plugs but with coil on plug.... I have never noticed anything.
I drive around 33k miles a year so I don't want to change much beyond safety and reliability items. So yeah I'm changing oil at 10k miles, cleaning K&N when necessary, and brakes/tires.
No plans to change any other fluids or items. Truck will be traded in about 2 years.
I will update if I notice anything good or bad.
These have been in my car for about 18 months, maybe 20k miles. Was driven 100+ miles a day in 2019, but have only put maybe 1000 miles on the car since March.
Question for some of you spark plug guru's....
Forget about brand, but what would be some common symptoms of spark plugs that may be TOO cold in heat range? Stumbling at part throttle or at WOT? Any experience here?
Stumbling at part throttle. Ran 542s when I ran meth alot more than I do now. Went back to 534s everything was all good then.
Yeah, I got that going on right now, part throttle stumble...with e85 I may not want to have as cold of a plug as the fuel burns at a lower temp...I've been thinking that's what my problem is as it didn't do it before the switch to corn but wanted to get some validation before I make the change…
I found that opening up the gap just a tad on the SVO running E85 allowed it to run better. Opened the gap from .26 to .29 and it idles better and is stronger up top.
hmmm, maybe I'll do that as well...I have em gapped to 0.26 right now
Maybe we can get some tuner feedback. I've never had issues with E85 and cold plugs before and I also run a tight gap for high boost. Just cold ambient temps and E85 don't mix lol.
If I could start it on 93 and then switch to E85 I would. It's been cold enough here to keep me on the 93tune. Sucks but it is what it is.
Maybe that's my problem. I could feel my car surging on the track with my meth on. I t went away with the meth off and I was running near the same ET.
