5.6 Lambda sensors important note:
Please ensure that a small amount of Copper grease is applied to the threads prior to fitting.
The Lambda Sensors fitted to each exhaust tail pipe are very
sensitive items and therefore, care must be taken to ensure that
they are not damaged.
5.7 Barometric pressure sensor important note:
Never install the sensor with the
inlet hole oriented to the top.
5.8 Air filter
Cotton air filter is an important and sensitive part. On dirty circuits, ensure to use exclusively new filter.
Keep in mind that a new filter is only pre-oiled; specific
COTTON
air filter oil (distributed by K&N, Green,
JR, DNA, others…) must be added on a
new air filter (each side) before to install it.
OIL FOR FOAM AIR FILTER IS STRONGLY PROHIBITED.
Air filter can be cleaned and re-used. It is important that your air filter be clean (or changed) regularly
to ensure an optimum engine performance and reliability. This interval can be greatly influenced by
your environment and driving conditions. In dusty areas, you may need to clean the filter more often.
Please refer to section 6.2 of the engine manual for air filter cleaning procedure. ORECA recommends
to customers to have a minimum of 2 spare air filters and a complete air filter cleaning kit.
