This is our custom vacuum line kit for the 20v 4age. You can choose the kit to fit either the Blacktop or Silvertop. We also have an option for those of you using the Silvertop with Blacktop electronics.


This kit will replace every vacuum line on the engine, including those under the ITB's, thus eliminating the possibility of a vacuum leak due to a cracked/dry rotted line. If you have ever had to trace down a vacuum leak this is the kit for you.

We have already cut the lines to size and placed them in individual labeled bags. Also we include detailed directions for easier install. We take the guesswork out of replacing the lines!

Our kit is made from professional quality high grade silicon and is available in your choice of RED, BLUE, or BLACK. You can add the lines that go to/from the A/C idle up solenoid and/or delete the engine hook if you like that cleaner look.

Please note that these line kits are hand made and take time. Please allow sufficient time for us to make this top quality part for you.

*NOTE* These lines are press fit silicon, very much like the stock rubber lines they are not held with clamps. On a non-forced induction engine you will have no problems with this. Although, if you have a turbo or supercharged engine you will require clamps to hold some of the lines on while the intake is pressurized above atmospheric pressure.
