Ruthenium plugs, who here has use them?

[felopr]

I switch from the ngk iridium 1 step colder plugs that everyone uses, to the new ngk ruthenium 1 step colder plugs.
If you go to NGK page and search the fiesta st, the only plugs that came back are the Ruthenium LTR6BHX https://www.ngk.com/NGK-Automotive-Parts-c1411.aspx
unlike the iridium that don't appear, either on stock heat or 1 step colder
I guess that was the reason i wanted to try them
Just change the 6 for a 7 (LTR7BHX) and that makes them 1 step colder.
I am on stock turbo with a dizzy stage 2 flash tune
The one that arrived where gap to like between 0.28 to 0.29 when i measure them with a feeler gauge, i gap them to 0.27 with a feeler gauge and a spark plug gap tool
The iridiums that i had before where gap to 0.26
I only have them install less than a day and from what i can tell, the idle and low rpm feels smoother in my opinion
Also the hesitation from when starting the car is gone, if you have use the iridium one colder spark plugs, you know what i am talking about. Or is it just me?
Just trying to gather feedback to see if anyone feel the same way as me

Interested I just bought the regular 1-step colder plugs this past weekend. Didn't know there was such a thing as a spark plug gapper tool, where can I get one?

@M-Sport fan recently installed a set, I believe.

Yes, installed them about a month or so ago.

The idle seems a bit smoother than the 20K mile factory plugs did, but I did not check the mileage since install, and since I got the factory heat range version of these (they DO offer a one step colder version as well), the WOT throttle response is very close to the factory igniters, and maybe a little bit smoother.

@ron@whoosh any chance we'll be seeing these on the Whoosh site soon?

Would love a pregapped option like the NGK iridium just because I'm too lazy to gap them myself lol.

lol, same.

I didn't really like how the car felt with the 1 step colder Iridiums. Curious to pick up a set of these but also wonder if anything would be changed from the Stage 2 Dizzy tune

 

[OguNinja]

I was just looking into these and your post just made me bit the bullet.
I need to change my plugs anyways.

Also, if anyone else is buying from NGK; you can get a free tshirt!

not really, the ECU itself is very smart, and any small variables the ECU just deals with it by itself

I bought mine from RockAuto though

 

[kivnul]

Just ordered a set myself. RockAuto is about $20 cheaper all in compared to NGK themselves. I do like the T-Shirt, just dunno if it is worth that much cash.

I'll definitely pick these up from you when they come in, especially when they're pregapped. Any idea when they should be in stock?

I'm going to go back to selecting gap also for both plugs .025 through .030

Just received theses plugs today from NGK. Set gap to .026. First impression is the engine fired quicker, idles much smoother, and the throttle response is a tad faster.
