"These are the common "9" Heat Range spark plugs used for the Honda B, D, & H Series Motors (Part # R5671A-9)and come in a set of four."

read descriptions much?

 

i know the link went to 9's but i was going to order 8's

 

I only pay $2 a plug for R5671A's, get them at your local Mustang shop

 

order 8's

You have no need for 8's with your power level. 7's dont fowl out nearly as fast.
