We remove the tip of the tube from the hole in the throttle body.
The connection is sealed with a rubber ring
On the K4M engine:
Disconnect the end of the throttle cable from the lever
Disconnect the wiring harness from the throttle position sensor connector.
With a head of 8, unscrew the two bolts securing the throttle assembly to the receiver
We remove the throttle assembly, overcoming the resistance of the sealing ring
Using a screwdriver, pry off the rubber ring and remove it from the groove of the nozzle of the assembly
We also remove the rubber o-ring from the other branch pipe of the assembly
On the F4R engine:
We press the locking element of the latch of the block of wires of the engine management system
Pry off the wire harness retainer with a flathead screwdriver.

Pry off the rubber ring with a screwdriver and remove it
To facilitate the connection of the throttle assembly with the receiver and the air filter housing, we apply a thin layer of silicone grease to the o-rings.
Before installing the air filter housing, we check the condition of the rubber bushing in the housing connection with the fitting of the cylinder head cover.
If the sealing sleeve is damaged or has lost elasticity, replace it with a new one.
When putting on the air filter housing on the nozzle of the throttle assembly, it ensures the connection of the sleeve 1 of the housing with the fitting 2 of the cylinder head cover.
