what wires shoule i use i have a d15b2 with a d16z6 head on it and i need to know what mm wire should i use 8.5 or are 10.5mm better?

 

plug wires im taking it your talking about, anything oem or above will do. Its really not going to make much of a difference at all. Accell thunder sports are fairly cheap and good and you can get them at your local parts store

 

oem!!!

 

All that size rating stuff doesn;t really mean anything.

Seriously get genuine Honda wires. they might cost twice as much as your local auto mZone crap wires, but genuine Honda wires have been dyno proven against many other "performance" plug wires sets, and they last the longest, and they don't come apart when you simply try to pull the out of the spark plug tubes to check your plugs. Aftermarket wires tend to be cheaply made and literally pull apart when simply trying to remove them.

Also many people will say "get NGK - they're OEM" but actually they are not. Years ago there was an article on TOV (Temple of VTEC) that detailed an old first-gen B16A shipped over from Japan and they dyno'd the engine after installing it into a DA Integra. After a base pull with the original old-*** Sumitomo (they make the B series wires for honda) they installed new NK blue wires and lost whp and the power curve was not as smooth either, indicated some break up in the ignition system/spark delivery. Swapped back to the old-*** Honda wires and it was smooth again.

I'm not NGK wires suck, because they're the best aftermarket wires - i'm just saying that they're not OEM like a lot of people think.
