You will receive two lines with this kit: (1) 4 foot line and (1) 5 foot line. If you are serious about buying this kit, make sure you measure the distance between the oil filter and the desired oil line route to the front of the vehicle. However short you keep the line, add another foot and a half. Just a warning. First of all I will come back to this review after the next trackday I do. I bought this oil cooler to keep the oil temp down while running my Civic at FULL THROTTLE. Hope that helps. When I installed this cooler I noticed that each line was a foot shorter for my application and the way I routed my lines. So I had to buy some wiring and extra fittings to make it work. I'll see how it works after putting everything together and stepping out of my car at the track.
