Assembly and disassembly instructions for the Power Box for the purpose of cleaning screens and filter.
Unbolt the four- 65mm screws from the velocity
stack base located on the corners of the base.
Once the screws have been removed, gently pull
the base out of the Power-box body.
Unbolt the four- 12mm screws from the velocity
stack base located to the center of the base. Now
separate the base from the velocity stack.
Loosen the clamp on the filter neck in order to
separate the filter and velocity stack.
Once the clamp has been loosened, gently
separate the velocity stack from the filter neck.
With the velocity stack base out of the way, the
rectangular pre-filter screen will now slide out of the
Power-box channel.
Unbolt the four-45mm screws from the Power-box
top. The screws are located towards the corners of
the top.
Once the screws have been removed separate the
top stabilizer from the Power-Box body.
The round pre-filter screen will now detach itself from
the stabilizer top for cleaning.
1. Upon completion of the installation, reconnect the negative battery terminal before you start the engine.
2. Align the entire intake system for the best possible fit. Once the intake has been properly fitted continue
to tighten all nuts, bolts and clamps.
3. Periodically, recheck the alignment of the intake system and make sure there is proper clearance around
and along the length of the intake. Failure to follow proper mainentance procedures may cause
damage to the intake and will void the warranty.
4. Start the engine and listen carefully for any odd noises, rattles and/or air leaks prior to taking it for a test
drive. If any problems arise go back and check the vacuum lines, hoses and clamps that maybe causing
leaks or rattles and correct the problem.
5. Check the filter for excessive dirt build up. Clean or replace the filter with an original Injen filter (can be
bought on-line at “injenonline.com”). Congratulations! You have just completed the installation of the best
intake system sold on the market. Enjoy the added power and performance of your new intake system.
