I've been looking recently to buy a crabs intake, but i dont really have any experience in the field. I was just wondering if I purchase O3, is everything I need included in this kit? And also how hard the install is. It's got great reviews and the price seems unbeatable so I'm very interested. I have a 3.5L V6 so I don't think I need a tune or anything, but I'm also curious if there is any modding I'll have to do after its installed.
