Hello, I have a 99 civic EX and it is EFI (electronically fuel injected) right? Well, I was going to order an skunk 2 intake manifold for it and was wondering if it came with gaskets and all the necessary hardware (nuts, bolts etc) that i would need for installation. Also, will i have to do anything else to my car (injection wise) to have it perform up to par? Nothing to enhance the power, just wondering if there was anything mandatory that i would need for this application and installation. Sorry if you can't understand that. I am just learning. if anyone has a website that they know of with good prices of these i will greatly appreciate it. Thanks in advance.
