Performance upgrades for the G80 3.8 engine

I am reading alot about the K&N air filters and JB4 tuner, but they are only available for the Kia Stinger (2.0T, 3.3TT), G70 (2.0T, 3.3TT), and G80 (3.3T). Basically, every flavor except for the 3.8 Naturally Aspirated engine.

So for those of us who may buy the lower end G80, what recourse do we have to upgrade the engine performance?

Not getting much response on this issue. Did see on you-tube a guy placing electrical tape over airflap magnet that opens above 4k - to open sooner. Not really sure it does anything??

Kinda sad when the only 3.8 engine mods recommend are a piece of tape and a new air filter. 😆

Oh well, if we really wanted more power we could have bought the more powerful engine.

I dont think you're missing too much. How often do any of us really open up the full capabilities of our vehicles? Most mods are an exercise in satisfying our desire to tinker. You have all that extra income at the end of the month to spend elsewhere.

I did the airbox trick on our 2012 but have not really noticed any difference but my wife drives it most of the time and she never notices much about the way it runs as long as the tires provide a comfortable ride. But I never noticed the hesitation that some people talked about either that led to the air box mod.

I suspect the design intent for that flap in the airbox is to allow the car to start easier from cold. I don't see how it'll help performance since at speeds, the flap will open anyway.

On my karts, when they fail to start on the 1st crank, we basically cover the air intake and crank again basically allowing it to run a little richer.
