The Injen 1035RED is a red Hydroshield water repellant pre-filter, a slip-on polyester sleeve that fits over the outside of a matching Injen cone filter to catch splashed water, mud, and coarse dirt before they reach the filter media. The manufacturer says the Hydroshield uses a proprietary base media treated with a hydrophobic water-repellent, and it is designed to enhance the efficiency of Injen's SuperNano-Web and 8-Layer oiled cotton gauze filters. The sleeve is water repellent, not waterproof, so it reduces the chance of a soaked filter in rain or puddle splash but does not protect against deep standing water. Owners on user forums are divided on power impact, with some reporting a small loss during wet running, so confirm details with the manufacturer if airflow is critical to your build.
This pre-filter is matched to filter model rather than to a specific vehicle. The manufacturer lists the 1035RED for Injen X-1010, X-1011, X-1017, X-1020 and X-1024 filters, which measure 5 inch base, 5 inch media height and 4 inch top, and it lists the same sleeve as compatible with the X-1010-BR and X-1010-BB filters. Enthusiasts searching for an Injen 1035RED, red hydroshield pre-filter for X-1010, 5 inch base cold air intake pre-filter, or red water repellant filter wrap will find this match. Because the sleeve depends on the filter's diameter and height, confirm your filter model before ordering so the Hydroshield seats snugly rather than sliding loose.
No. The manufacturer describes the Hydroshield as water repellent through a hydrophobic treatment and states that it does not make the filter waterproof. It is intended to help block splashes and spray, not full submersion.
The manufacturer lists the 1035RED for the X-1010, X-1011, X-1017, X-1020 and X-1024 filters, all of which are 5 inch base, 5 inch media height and 4 inch top. Check your filter model number against that list before ordering.
The manufacturer lists the black 1035BLK for the same filter group, so both colors are offered for the same filter sizes. Choose based on the color you want, since the fitment list is the same for both.
The pre-filter is a slip-on accessory that sits over the outside of the filter, so no cutting is needed for a standard fit. Remove the filter from the intake, slide the sleeve over the filter, and reinstall the assembly. Owners on user forums mention that some intake setups may need modification, so check clearance between the filter and the intake tube before you begin. I could not locate a manufacturer install sheet for this red part, so confirm steps, tools, and torque requirements with Injen before starting.
