Volkswagen Amarok MY23-26Twin-Pod Airbox

Park on level ground and open the bonnet. Disconnect the battery's negative terminal.

Lay the kit out and check it against the list above. Keep the factory parts you take off until the install is finished: the MAF sensor is reused.

Find the MAF (air flow) sensor plug on the factory airbox lid or intake pipe.

Press the locking tab and pull the plug off. Pull on the plug, never the wires.

Loosen the hose clamp where the intake hose meets the airbox, and the clamp at the engine intake end.

Work the hose off both ends and lift it out. Cover the open intake with a clean rag so nothing falls in.

Undo the bolts and clips holding the airbox down, then lift it straight up. It takes a firm pull to free the rubber mounting feet.

Put it on a clean bench. You'll move the MAF sensor across from it.

Bi-Turbo: the factory resonator isn't refitted. The resonator delete (AMK-G2-RES) takes its place.

Undo the two screws and lift the MAF sensor out of the factory airbox.

Sit it on the CannaFab MAF housing the same way round as it was in the factory part: the airflow arrow points towards the engine. It must sit flat on its O-ring.

Fix it to the housing with the M3 bolts (2.5 mm Allen key). Snug, not tight.

Turn the airbox over. Bolt the feet bracket to the underside with the four supplied M5×15 bolts.

The bracket's feet push into the factory airbox mounts, so check they line up with the mounts in the engine bay before you go on.

Bolt the washer bottle to the airbox. Move the factory washer pump into the new bottle and use the supplied hose to extend the washer hose. No wiring needs to be cut.

The Volkswagen Amarok MY23-26 snorkel guide has the washer-bottle steps in full.

Lower the CannaFab airbox in under the factory intake pipe and push its feet down into the factory rubber mounts until they seat.

Check it sits level and clear of the bonnet, brake lines, wiring and anything that moves.

Push the factory intake pipe onto the airbox outlet and do up the factory clamp.

Open the lid and check the pod filters are seated square on the inlets with the clamps tight.

Check the lid seal sits in its groove all the way round, then fit the lid and do up the lid bolts (4 mm Allen key).

Set the drain valve on the bottom of the box: open for everyday driving, closed for water crossings.

Push the factory plug onto the MAF sensor until the lock clicks.

Check the wiring has enough slack for the engine to move, and clip it back where it was.

Check the intake pipe clamp. Check the feet bracket bolts and the MAF bolts.

Make sure no tools, clips or rags are left in the engine bay, then reconnect the battery.

Start the engine and let it idle. Listen for whistling or sucking noises at the intake pipe and the lid.

Check there are no warning lights. Take it for a short drive and check the clamps and bolts again afterwards.
