There is lots of opinions on which spark plug to use on the 90 to 94 Daihatsu Hijet S82P/S83P. What is everyone using? So far I've seen: NGK Bpr5EKB #5449 NGK Bkr6E #6962 NGK Bpr6e #6464 NGK Bpr6ey #6427 NGK Bpr6es #7131 Champion RN9YCC
I'm using Champion Iridium 9804 heres a list I posted with all the available options for all Daihatsus and Atrais
Yes I did reference your list when making this post. It shows the NGK BPR5EKB which is not available in Canada.
another good tool for all makes I'll post this in a general section as well http://www.sparkplug-crossreference.com/
I know this is an old post, but hoping I can revive it to get answers from you knowledgeable folks. What size socket to use when removing said spark plugs? I have been unable to get mine in there and mine did not come with a tool kit like it seems everyone else's did.
I spent two hours trying to get mine out this weekend. The new plugs are 13/16, so I tried that. Didn’t work, tried the 3/4. Didn’t work tried 18-mm. Didn’t work, tried the 5/8, and it finally did. So, if you have the stock Japanese multi-electrode spark plugs, it’s a crap shoot. If you have the NGK BPR6ES, or something similar, it should be a 13/16.
they are pre-gapped.

which spark plugs did you end up going with? I have the same truck. lots of info out there on the EF-NS, EF-ES, and EF-TS engine. but NO info on our EF-CS engines. Im leaning towards doing the ngk BPR6
The important thing is that the dimensions, for thread, reach, etc., are correct. Then look at heat range. You probably won't find the coding information for the spark plugs in the US or Canada. I looked up an NGK EU catalog, and it had the coding table, and back coded to determine the dimensions of the stock plug, and the heat range. The North American catalog uses teh same coding, so you can figure out what NGK plug you can buy in North America. Once you have that, you can cross reference to other manufacturers. The list above is pretty good, I think the "E", extended is critical to position the electrode correctly in the cylinder head, and assure good ignition. I've been running the NGK Bpr6e #6464, for eight years. They look right when I pull them to install new ones. I tried the BPR5E originally, but they had the wrong color when I pulled them after a month to see how they looked. If you watch sales you can buy them in sets of six on sale, and buy wires for a six cylinder car, and crimp on new ends to make them right for the EF engine in your Hijet. You can buy the wires, crimp ends and crimper for less than a set of fitted wires from Japan.
been doing A LOT of shopping. I need to order more parts as well. so i think these plugs weither i get 5 heat range or 6 is where im confused on where to go. I do know i can make the spark plug wires. as i actually already have the crimping tools and plug wire to make my own. I would just need both ends of the wires. I made plug wires YEARS ago for a mercury 80HP outboard 4 cylinder, and i made some for my 1958 farmall cub. Here is where i found plugs and through decodeing of the plugs it looks like i can do the BPR5EKB here. Or if in the US (like i am) looks like the BPR5EKU would also work. https://www.blackhawkjapan.com/products/ngk-bpr5ekb-5?variant=51256913232163 https://www.blackhawkjapan.com/products/ngk-bpr6ekb-5?_pos=1&_sid=65060c5d4&_ss=r
I used to use NGK, but found the Champion Iridium to be superior. Easier start, better throttle response, and last about 3x as long without having to clean them
