repairer (we recommend an Authorised Mazda Repairer) for details.
*2 Because the SKYACTIV-X 2.0 is a high compression ratio engine, the piston and plugs are close to
each other. If the replacement is not done using the correct procedure or a non-genuine plug is used,
the engine could be damaged. Consult an expert repairer (we recommend an Authorised Mazda
Repairer) for details.
CAUTION
When cleaning the iridium plugs, do not use a wire brush. The fine particulate
coating on the iridium alloy and platinum tips could be damaged.
