This modification is probably the easiest modification I have seen yet. It requires 3 things. By using the three things together you can pretty much rest assure that your air filter won’t becoming off anytime in the near future.
Please note this project was done with the Hyper .21 8 port engine installed on the HPI Savage.
Parts and Tools Needed:
(1) HPI High Performance Air Filter (part no. 72438)
(1) Traxxas Rubber Pipe Exhaust (part no. 4451)
(2) Small pipe clamps
(1) Flathead screw driver
1. Take the 90 degree elbow that comes with the air filter off.
2. Attach the Traxxas Rubber Pipe Exhaust (4451) to the end of the air filter, then use one pipe clamp to secure the two together.
3. Attach the Pipe Exhaust with air filter to the carburetor, then tighten the second pipe clamp to secure the entire thing to the carburetor.
4. Go outside and bash your R/C now cause your finished!
Notes: The nice thing about this setup is that the pipe exhaust is thick enough to support its own weight plus that of the air filter, thus not needing ANY other hardware to hold it up. On top of that this setup is perfect for the HPI Savage, as it clears the spur gear completely.
Traxxas Exhaust Pipe (4451) – $4.29
Pipe Clamps (2) – $1.00
HPI High Performance Air Filter (72438) – $16.95
