AMS Turboback paired with STM atmosphere 02 Dump. Car absolutely rumbles and snarls, I love it. Picked up 500rpm of spool easy, and some decent hp/tq gains.

 

cams and bigger turbo

 

My street glow under the car Neon lights Fast&Furious Green.

 

Snow tires.

 

My IX is mildly tuned: Hallman MBC, Works TBE, Buschur FMIC, and a very good tune from STM. The parts have been on my car for 6-7 years and I never think about them. That's a very good thing in my book.

This being said, my favorite mod is a factory trunk net. Best $25 I've spent on the car. It prevents packages from turning into cruise missiles on the way home from the store.

 

Bump cause I love this thread

 

Suspension for me, AST 4100's and sway bars front and rear.
