There are multiple problems with the cap/reservoir
1. Positioned too close to headers. Dodge solutioned this by applying a temp resistent plastic on one side of reservoir but it still goes through a wide range of temp changes during use.
2. OEM cap has small rubber seal on inside but it does not adequately secure the cap during the temp changes. One day, and you'll never know, it will work it's way loose.
3. Vent nipple on OEM cap tends to blow out fluid during hard cornering.
4. Same cap/reservoir on all 92-02 Vipers.
This product is a nickel or chrome tube, Viton rubber connector, stainless clamps, and tie. Once the OEM cap is on, you attach this to the nipple on the cap. The clamps aren't user friendly, but high quality, excellent looking, and they snap shut and lock the tube. Makes it impossible to turn the cap.
Easy to remove one clamp for fluid changes once a year.
The hollow tube does not restrict venting of the reservoir which is critical. During track use, if any fluid makes it up the tube, it will safely exit below the reservoir, not on the headers.
