Steps

1. Remove the battery cover

   • Take off the plastic cover over the battery. It's in the way of the airbox.
   ▶ Watch this step (1:22–1:37)

2. Disconnect the intake tube and MAF

   • Remove the two 10mm bolts, loosen the hose clamp on the tube, and unplug the airflow (MAF) sensor by lifting its tab.
   ▶ Watch this step (1:37–1:52)

3. Unbolt the airbox

   • Remove the airbox screws on each side. A long Phillips screwdriver makes these much easier.
   • The back bolt is tight against the strut tower, so use a socket with a swivel joint. Taking the MAF sensor out first gives you more room.
   ▶ Watch this step (3:13–4:16)

4. Lift the airbox out

   • Pull the rubber mount free, then push the airbox up and to the left to lift it out. Remove the small piece left on the bolt underneath.
   ▶ Watch this step (4:16–4:32)

5. Fit the new airbox and filter

   • Bolt the new heat shield to the battery tray and the strut tower bracket, then fit the filter with its rubber seal and the screws from the kit.
   ▶ Watch this step (4:32–5:03)

6. Reconnect the MAF and breather

   • Fit the MAF sensor and plug it back in.
   • Push the small breather filter onto the hose that used to go to the airbox, and secure it with the clamp or a zip tie.
   ▶ Watch this step (5:03–5:33)

7. Test

   • Start the engine, check for a check-engine light, and refit the battery cover.
   ▶ Watch this step (5:33–6:05)

8. Unscrew the airbox lid and clamps

   • Remove the Torx screws around the airbox and release the spring hose clamps (pliers or a flathead).
   ▶ Watch this step (Stevolution, on a Mk2 TTS) (1:22–1:34)

9. Lift the airbox out

   • Remove the bolt by the box, the bolt on top and the two screws on the front scoop, then pull the box firmly up off its rubber mounts. It feels tight but won't break.
   ▶ Watch this step (1:34–1:58)

10. Check the kit and bracket

    • Lay out the kit: inlet scoop, seals, hoses, filter and bracket, and check it matches your car's airbox bracket.
    ▶ Watch this step (1:58–3:43)

11. Fit the mount and bracket

    • Swap the old screw for the new mount from the kit (it screws in all the way so the rubber cup sits on top), then bolt the bracket on. Note one bolt is 10mm and the others 11mm.
    ▶ Watch this step (3:43–5:08)

12. Fit the filter and MAF sensor

    • Move your original airflow sensor into the new housing, connect the filter and hoses, tighten all clamps, and plug the sensor in.
    ▶ Watch this step (5:08–5:45)
