Yes it's me again , I am wondering if any of you have replaced your plugs, AutoZone recommends the NGK Iridium/Spark Plug. I believe the factory uses the same one and I find NGK over my last vehicles to be excellent and preforms better than any other one I have tried in the past 40yrs.
I have heard that the Iridium/Spark Plug is good for 100k miles but there is no way I will follow that. Have anyone changed their Soul's 2.0l before 100k? Do you have a regiment for plugs?
Hi on diesels now but would not rely on plugs after 50-60k miles would rather have preventative maintenance and keep tip top spark than run risk of miss fire and causing damage to sensors and all that may be involved.
Last set I had said 60k but after 40k performance seemed compromised gaps were 50+ ths '' not 32-40 as recommended.
New plugs car was driving as new.
I have not replaced plugs on a 2012 Soul (have 50K on the one with the most miles and 47K on the other and they show no signs of wearing); however, I have on some other cars. On a 1998 mustang I replaced them once in 247,000 miles because they were only bad once (Iridium). On a 2003 Toyota Matrix I never did replace them in 125K miles because they never needed it. And finally on a 1995 F150, I also did not replace them at all in 108K and it ran like a top in all that time.
In the past 25 years, I've only replaced one set of plugs. That was on my Suzuki Grand Vitara (V6) at 100,000 miles.
I could have dusted off the OEM plugs and put them back in, as they showed no signs of wear or burning.
I used the recommended Factory replacement plugs. I think they were of the Iridium type. Bosch, I believe.
Back in the days, when I was driving Detroit Iron, we changed plugs about every 30k miles, or sooner.
If everything works out according to plan, I should Never have to change the plugs on my Kia Soul.
I'll be changing my 2010+ plugs soon (~60,000 miles), converting those over to Autolite Copper plugs because I've seen a recent drop in mileage, so we'll start there.

Right on the money , had a friend with a Hyundai that came with iridiums , replace them with copper , right off the bat the car performed worse with copper than the old iridium plugs that he replaced . And that was in the same engine that is used ( was used ) in the Soul , 2.0 beta II
I'm not a Master Mechanic, but just a mid-grade Mechanical Engineer, and I'm certain I could find where the lost MPG's are going, in ten minutes or less. Cars are a long ways from 'Rocket Science'.
I fix computers for a living and cars are not that different.
As cars get older, they require difference maintenance.
From day one, to trade in, I always maintain my cars the same way. (with lots of TLC)
They seem to love me for it too! Because they always give me great performance.
I get great mileage from my little Gertrude (Kia Soul 1.6L) as seen on the above pic.....my Scan Gauge II.
Taken on my last trip to Daytona Beach, FL.
Tech, I think it is great that your Soul gets such great mileage but it is hard to believe to say the least. Don't take this wrong, I do not think you are lying at all, lets get that straight first thing
Do you think the 2.0 is capable of the same or even maybe 42mpg? Does the scan-gage really help or could you accomplished the same if you didn't have it? I just want to know this before I spend the money, do you think I would be satisfied if I bought it?
I use a harpoon and spearhead large tractor trailers going in my direction.
It's not uncommon to get 99 mpg's with the draft in place.
60+ mpg's...I think it's time to have the scan gauge tuned up!
I have purchased Autolite Iridium for about a buck a plug for my Gsxr's.
Autolite had a 2.50 per plug rebate at the time.
Needless to say I bought 10 boxes of them!
