I bought these from KERTWOOD, he shipped asap. When they arrived, they were the two hole, and I wanted the four hole. He never said they were the four hole, I assumed they were. I contacted KERTWOOD, and he refunded me the money for the injectors back, and told me to keep them. Little background story. Now, I will ship these injectors to anyone in the states for $10.00. KERTWOOD payed it forward to me, and I am passing it on. Please respond to this post, not pm. I will ship to whoever has the first post for $10.00.
