Engine?

ive been looking through some of the pics.. and saw a lot of engine pics with color "hoses" (i guess that's what they are called). did you guys buy then and just wrapped it around the lines? where can i find some? my car is white so I want to have some white under the hood.

Any auto parts store such as, Autozone, Advance Auto etc should have engine dress up kits that come with the colored hose etc..... And I belive you can buy the different sizes in bulk from places like Jegs.com and summitracing.com
