I there guys I'm building a d16 all motor high compression and i will like to know what spark plugs should I use? the comp is going to be 12.88:1

 

Wait for someone else to chime in but I would say one step colder than stock, the higher compression would warrant a colder plug, I believe this is to ease off predetonation. I am sure someone will chime in with exactly what you need.

I would, however, recommend NGK's as they are cheap and good performing plugs.

can you give me a part number?

 

NGK FTW

 

This helps noone, it would help if you would stop running up your post count with useless posts.


OP: I am assuming you have a d16 from our year Si, so this is the part number for a stock ngk-BCPR6ES-11 and I assume that one range colder would be BCPR5ES-11. Hope this helps, a simple search on google provided me this information off of NGK's website.

Alex

 

Thanks and i'm using a ZC sohc so basicaly is a d16a6 (civic 90 si)

 

you can buy all NGK items from that engine direct and for cheap on www.sparkplugs.com

 

What don't you ask the person building your motor? And if you are building it yourself, why not ask people or search on what information goes into selecting a plug for a certain setup?

 

1 step colder is ngk-BCPR7ES-11 - the lower the number, the hotter the plug

 

Thanks for the recommendation of NGKs. I will check out www.sparkplugs.com to buy direct.
