NGK Honda CBR300R Laser Iridium Spark Plug

The NGK Laser Iridium Spark Plug (SIMR8A9 / 91064) is the premium upgrade choice for your Honda CBR300R (2015–2022 models), delivering superior ignition performance, longer service life, and reliable starts in a high-revving single-cylinder sportbike. As NGK's top-tier Laser Iridium series, it's engineered for demanding applications like the CBR300R's 286cc liquid-cooled engine—whether you're commuting, canyon carving, or hitting the track.

This plug is the direct OEM-equivalent replacement (often factory-installed or recommended), featuring advanced laser-welded fine-wire iridium center electrode and platinum-tipped ground electrode for exceptional durability and efficiency.

Note: Always verify gap and torque during install; pair with fresh NGK plug cap/wire if needed for best results. Not intended for heavily modified engines without tuning—consult a mechanic for tuned setups.
