hello , I have a 1999 3.8 v6. I saw a post here asking what was the intake , and it happened to be windstar. I like how it looks and I wild like to attempt myself. now as I've looked over the Internet, and im confused to which intake pieces I need. from my understanding, the intake is made up of the upper and lower parts. but some of the pieces I've seen have had some parts named "center" for position. making that the 3rd piece?. could someone point me in the right direction which intake parts I need for my year ?
