Hi Bro, I'm Midass from Amaze Autoparts, we are NGK Spark plug reseller.

Just for your info, the model you looking for which also follow your user manual DILFR6F11G was OE code for Honda and they have a contract between them, mean NGK only can supply this exactly model code to Honda.
For aftermarket (which supply to spare parts shop or reseller like us), they use different plug code so it will no conflict with the OE contract but the size and spec of spark plug was exactly the same with DILFR6F11G.

Now we are running Merdeka promo in Lazada, with 10% Discount, below was the link:
NGK Laser Iridium Spark Plug for Honda Jazz Hybrid (8ps/set)

All our stock was guarantee genuine because it was from NGK Malaysia, no any other source we carry in the spark plug.

By the way all Honda engine design after year 2005 was originally fit with NGK Laser Iridium Spark Plug as manufacturer need to maximize the combustion power also the change interval of spark plug is longest (NGK Laser Iridium Spark Plug could last 100,000KM)

Thanks.
