U24FER9 Spark Plug from Denso
* About quality and texture, This is a 10mm in diameter nickel spark plug and a substitute for what comes in the Takegawa 181cc 4V big bore kit for the Honda Grom, featuring a 2.5mm diameter non-projected nickel electrode. * About the feeling of use, This spark plug's performance is what you expect from a standard spark plug and is sufficient for running such a high performance engine like the Takegawa 181cc 4v big bore kit without failure but will require more frequent replacement when compared to an iridium spark plug. * Products to buy together, The Honda OEM ignitional coil's performance becomes poor in the higher engine RPM range so the hyper ignitional coil from Takegawa is recommended to resolve this issue. * Difficulty of installation, Installation is just removing the spark plug cap a, swapping out the spark plug and torquing to spec. The process was completed in 5 minutes with no difficultly. * Cost performance and comparison with other products, This Denso nickel spark plug is priced just slightly higher then the compatiable version from NGK. Price differences between Denso and NGK are very minor and not the deciding factor between choosing a spark plug. * About shipping and packaging, I am happy to wait 8 weeks on average for my parts to arrive in Sydney Australia via Webike's sea freight which comes with tracking and insurance so I know I'm covered in case something was to go wrong but with there outstanding bubble wrapping and boxing there have been no problems. * Any concerns, cautions, or advice when purchasing, Use the NGK spark plug cross reference and comparer when researching options for you engine.
