New owner questions

I have a 2019 N Line and I am pondering modding it but I'm not sure. Your thoughts on the following:

Performance filter vs. Intake

Intake worth it without a tune?

I don't think an intake is worth it. The current one is already grabbing air from the front grill(ie: amoung the coldest places to get it) through a scoop.

If you want hp/torque gains with this car without swapping the turbo your basically looking at:

Highflow downpipe and cat-back exhaust.
Tune and run 93.

Then maybe adding an intake might push out a few more HP.

Thank you for the input. I thought about the intake because it doesn't have a MAF and with the turbo sucking more air its claimed that I can get 10 hp. However, Maybe just a K&N or equivalent for better airflow. Its just my daily so I probably won't tune it or swap the exhaust because it sounds great for me. My other question is when moderately accelerating from say 40-55 I get this surge sometimes. I've read that it has to due with the factory wastgate but apparently Hyundai went to an electronic one for 2019 so its pointless to upgrade. Your thoughts?

When you say you get a surge, do you mean you get more power all of a sudden? It's possible, depending on your throttle position that you're just getting in the boost.

What gear are you in when this happens and how far on the throttle are you?

Its more like a hesitation but since I switched back to 87 octane it has pretty much stopped. It could also be the car still breaking in , I don't know. It does not do it in manual mode, but again it has pretty much ceased. I've never owned a turbo car as I prefer N/A cars, however they seem to be scarce these days unless its a V8.

So I just spoke with a guy at AFE and he said they dyno’d a 2019 n line with no tune and gained 14 hp. You think he’s full of it? Because if not this would be a worthy upgrade over just a filter and it should give more throttle response and possibly get rid of the surge.

It's not a 'bad' upgrade, but 300-400 Canadian for 14HP is not good value. I saw your other post saying that they acutally dyno'd a stock n-line and gained HP --- which is pretty interesting!

The Dyno's that AFE has on their website are on the Elantra Sport, and it's running a catback exhaust when they show the HP gain.

If you are frequently WOT throttle you *might* notice that gain, and ultimately what it comes down to, is if you want to do it; do it!

I'd personally put that 300-400 towards something better like a downpipe, catback, tune, or better tires -- but I totally understand wanting to do an intake.

Intake does result in a power increase.
Moreso with a chip or a tuned ECU
Mild increase in power (negligible almost) but a noticeable increase in "rorty sounds" if you swap out the intercooler resonator. It's only like a $25 part anyhow, cheap effective mod.



Some vendors, such as SXTH Element (check them out) have all sorts of mods for these cars. Including an up-rated boost solenoid, which can help alleviate surge whether stock OR modified.


Etc. Plenty of threads here and there with people listing mods.

Well being that it’s my daily and it’s new, I do t want them to give me a reason to void my warranty even though I k ow the part itself has to cause the issue. I do like the idea of the solenoid for the surge. I will mod the crap out of a toy but this is t it. I think I’ll do a panel filter and AFE said they are working on a handheld tuner that I can swap back and forth if I have to take it in. Thank you for all the input.

Hi!. I have a 2019 N-Line manual, that I've had for 2 months and 2000 miles. I bought an Takeda intake from aFe, utilizing an aFe dry cone filter. They advertise a 10-12 HP bump, and have dyno reports to back it up. I've used these folks before fir other "tuning" mods to cars,m and their products seem to work, as advertised. Since I've installed the intake, I can notice an increase in 3rd and 4th gear "pull"as I fully accelerate. I believe that it is worth it. And, right now, it is one of the few "easy" mods that are available.
