Hi all wanted to know if there are any performance enhancements for the 2009 3.3 v6 sonata engine besides turbo and nitrous and if so what are the horsepower gains the 249 hp seems to be great just wondering if you can get more without ruining the warranty.

 

No, there are no real upgrades to your Sonata that will not affect your warranty. The 3.3L V6 Sonata is a very powerful car for a daily driver. If you want more power, I'd suggest trading it in for a V8 Genesis or some other vehicle.
