Protecting the air springs
The bodywork must have a partition protecting the air springs separating them from the wheels and preventing damage caused by
sand, mud or stones.
The partition must leave a free space of 350 mm around the spring and must not obstruct access for inspections and maintenance
of the other suspension components.
2.10 MODIFYING THE ENGINE AIR INTAKE AND EXHAUST SYSTEMS
Note
The characteristics of the engine air intake and exhaust systems must not be modified. Modifications, if authorised by IVECO, must
not vary the original intake vacuum and exhaust counter-pressure values.

tions and at full load

Intake
The air intake must be mounted as to avoid intake of hot air from the engine compartment, or dust and water.
The intake compartment must be sealed airtight and fitted with rubber gaskets that prevent hot air recirculation. The gaskets must
be of high quality as to support a steady temperature of 100 ºC, with short durations of 120 ºC, without undergoing visible de-
formations or deteriorations. The compartment must keep airflow sections efficient for the entire circuit.
The holes that must be made in the box part of the van must have an area of about twice that of the cross-section of the pipe
upstream of the filter; these openings (e.g. grille holes) must have minimal dimensions to prevent possible clogging.
The following are not allowed:
●
alterations or replacement of the original air filter with one of lower capacity;
●
modifications to the silencer body;
●
interventions on equipment (injection pump, control valve, injectors, etc.) that may compromise good engine performance
and affect exhaust gas emissions.
●
change the succession Humidity sensor

Lastly, it is necessary to check if new system approval is required in relation to specific national standards (sound level, smokiness).
