Replacement parts and accessories
The parts making up the emission control system in your product's engine have
been specifically approved and certified by the regulatory agencies. You can trust
that the replacement parts supplied by customer service have been manufactured
to the same production standard as the original parts. The use of replacement
parts or accessories which are not designed for your engine – may negatively
affect the engine emission performance. Therefore only use replacements parts
and accessories from a qualified service centre to guarantee that the replacement
products will not adversely affect emission performance.
Replacement parts other than those from an authorized service centre will void the
warranty.
