This is extremely easy. Probably a 2/10 for difficulty and mainly self-explanatory.
1) Remove intake snorkel
- Loosen two Phillips head snap clips to release snorkel
2) Remove OEM elbow
- Loosen hose clamps on OEM elbow - one at the turbo inlet, one at the stock airbox.
3) Remove MAF
- Unscrew the two small Phillips head screws.
- Pull out MAF, unplug sensor and tuck away until later.
4) Unscrew 2 x 12mm bolts securing airbox
- One bolt is at the 3 o'clock position looking down on the airbox
- The other bolt is secured to the chassis right below the headlight.
5) Pull your airbox and silencer free (they'll come out together)
You're done.
