basic mods to get started

hey everyone, i love this forum and has helped me get to know my new golf very well.

i have recently bought a used golf 4th gen. GLE, and am now looking for a bit more power from the little 2L engine, and im woundering what are some good basic mods that don't cost to much and bring a decent outcome. i know i'am not looking for 500hp gains, just a few simple things. i have seen that a cold air intake is a reasonably good way to go, what brands would you guys and gals recommend ?? also i was looking at a tune at bps tuning in brissy, but is it worth the money for the stage 1 tune ? is it a noticeable difference. also where would i go to get these cold air intakes ? what kind of car shops would stock them ? is it a simple thing that i could install myself at home, (limited mechanical knowledge though).


thank you for your help !

Cold air intake, cat back exhuast and a after markey CHIP.

Is your car a 20v or 8v?
