Thanks, what is that...? I think that is an NGK number, but they now say nothing for the 2.0 premiums.

 

[Rodtheviking]

NGK number

92422 should be the stock number

 

[stinger541]

Thanks, exactly what I thought, but here you can see what I mean. Crazy town. I am wondering if that bulletin I posted where they changed the plug design has something to do with it....but then what do we use now lol? I am considering the HKS now but do not know if it is ok for just stock.

No more funny cat videos for you homie! Both numbers say they dont work for the 2.slo.

Are the ones I found that listed fitting the 2.0

Well.. I found them in the past but now NGK says they dont work.

My bad

 

[stinger541]

How? Where? I am on the NGK site right now and it is saying no, just like the pic I posted. In fact, once I put in the vehicle, it says we do not have any spark plugs for your vehicle. Am I in the multiverse or something?

 

[Rodtheviking]

Best I could do, I used the number on the plug to cross reference.

Genuine OEM 18857-09085 PLUG ASSY-SPARK 4 PCS Set / 1885709085 for select HYUNDAI KIA models https://a.co/d/cuqiiQ6

Thanks! Don't know how you did that, lol. That looks like it has to be it...same exact number as what was in that bulletin too! Just so crazy that NGK's own site says nothing available, etc. Wonder if it is a licensing thing or something, can only sell through Kia (or wherever you can find them).

So now I am going to order those unless someone tells me the HKS is worth the 120 bucks and safe for a 2.0 stock car?

Save your cash until you have a tune coming your way.

What does a tune do? Just increases the boost (and therein, remaps fuel/spark timing) correct? Is there a point to doing that on the 2.0? I have been thinking about trading this one in for a 22 or 23 gt-line for the 2.5 engine. But annoyed by some changes they made, like taking out the front parking sensors, the ambient/mood lighting, the sunglasses holder, and the seat memory settings. But if I get a tune for the 2.0, would I see a big increase in power...and a SAFE one? Like, not wanting to ruin the car prematurely. I already use 91 or 93 octane.

Its kind of a tough question to answer, really depends on what you want. Piggyback tunes are the least expensive route and definitely will get you more go. A full ecu tune will be more consistent and smoother through out the power band. Most popular by far on here IMO would be the Jb4. Plenty of support and lots of options and engine safeties built in. All my experiences with it are second hand, lots of friends running them. I surprisingly enough do not have a Jb4, im running a lap3 unclechip. (They dont sell it anymore)

HP wise you can get a decent jump. Just some reference #'s for you. With my bolt ons and chip my 2.0 hit 271 at the wheels on the dyno. My friend with his 2.5 hit 273 and he is stock with a K&N filter only. Stock hp from Kia 2.0 - 255, 2.5 -300. Of course those are at the motor.

Not a ton out there for us 2.0 guys but still enough to look at.

We are running NGK ILKR9Q7G Laser Iridium spark plugs in both our 2.0T Stinger and G70. 1 heat range higher than OEM. We've done AutoX and Track Day, with no issues so far. Veloster N and Elantra N guys run them too.

Reposting my own post from page.1 of this thread. They have been running just fine for the past 1+yrs on both cars. If they are incompatible, these plugs sure didn't get the memo.

Online documentation can be iffy. A lot of the sites are just vendors selling sparkplugs and not officially affiliated with NGK corporate.

 

[stinger541]

Thanks guys...I am looking at the RaceChip thing now, and the JB4. That one seems complicated though. I like just plug and play, so maybe the RC for me. I do not want to have any sort of drop in mileage, which is why I got the 2.0 in the first place. I believe the tunes would kill the mileage.

Volfy, thanks, I went directly to NGK and that is what it shows (I did look at other vendor sites too of course). I ended up buying the NGKs that were linked to me in this thead by Rodtheviking. This thread might be helpful for others, especially after learning that they issued a TSB on the plugs for at least the 2018 Theta II (2.0). I am hoping I will see an uptick with new plugs, gapped properly. Will also be interesting to see if any oddities with the plugs, like cracks or weird gaps.

JB4 is about as plug an play as it gets. Basically 3 plugs on the engine + the OBD2 port. I stay Map 0 for daily driving, as I have zero need for street heroics. It is exactly the same as running bone stock. On my morning commute right now, not needing to run A/C just yet, I'm getting 35+mpg indicated. I only switch to Map 1 or 2 for AutoX or track day, mostly to get the turbo to spool up faster and minimize turbo lag. Love the flexibility of it.

What was explained to me, which ultimately came from Nathan at SXTH tuning, is that with a piggyback, it is only fooling the ECU to provide more boost than stock by scaling the signal from the MAP sensors to the ECU. Telling the ECU it has less boost than it really does. In this case, you need better plugs gapped narrower because the ECU is providing spark energy, dwell and duration based on lower boost than you really have.
If you have a true ECU tune, then it can provide the correct spark parameters for the actual boost, and the plugs are not as critical.

 

[stinger541]

So is the jb4 an ECU tune or piggyback?

 

[Deviate]

Piggyback. It's actually a great unit. The logging of how your car is running is super helpful as well. Plus the support from Terry at BMS on here and members that know a ton is super cool

Terry can also provide a back end flash for those that have an EK1 tuning platform. I run this and it gives me the same performance as map 1 or map 2 without a jb4. I still use my jb4 for WMI and logging though.

Thanks for the add on!
