RC racing injectors 440cc. work great bought new mainfold and I cannot use these anymore. selling at best price offered.

 

will they fit on a d16Z6?

 

I believe these will work with any series of motor as long as you have the proper injector seals. Here is the list from RC Engineering. (http://www.rceng.com/prices.htm)
You can also get most any injector seal from your Honda - Acura dealer for really cheap. All my injector seals ran about $1.30 ea, and the spacers were around $2.50 ea.
