※ If you have a big bore installed, then we strongly recommend to install the NGK CR spark plug type (such as the CR9E LINK or the iridium version CR9EIX LINK) instead of the stock/standard NGK CPR type, since the shorter Non-Projected CR ground electrodes are less prone to detonation compared to the longer projected CPR electrodes.
If you have a dome piston then the shorter electrode will make the install also easier by lowering the risk of piston contact.
