Courier driver looking to enjoy the drive more.

[40mpg]

Let me start off by saying I love my 09 Sedan. I bought it with 172k in June and it just rolled over 250k last Thursday. Amazing car. I want to hit 350,000, but I also want to enjoy the car a little more. Here’s what I’m thinking.
-K&N CAI
-H&R springs
-Wheels 15-17”
-a quit quiet muffler/cat back.

Interior: This head unit from EBay https://www.ebay.com/itm/Car-DVD-Pla...-/132568219591

And a TRD shift knob and window tint.

It’s also going to need a clutch sooner rather than later, what’s the best out there that’s closest to OEM?

And also, I want to replace all speakers with good quality stuff, even though mine has “premium sound” I feel there’s better options out there. Any suggestions on these or the clutch? It would greatly appreciated.

Thanks,
40mpg
