The Injen Hydroshield 1038BLK is a black, cylindrical water-repellent pre-filter that slips over the outside of a compatible Injen cold-air filter. It is built from polyester with a hydrophobic treatment, which the manufacturer says helps repel water and keeps the filter cleaner by catching larger debris first. The manufacturer is clear that it does not make the filter waterproof, so it suits splash and puddle exposure rather than deep-water crossings. Compared with running a bare filter, it adds a sacrificial outer layer that shields the element from contaminants, which the manufacturer says extends filter service life. It is backed by the manufacturer's limited two-year warranty on Hydroshield products, so the cost is easier to justify for a daily driver or track car that sees wet pavement and dusty sessions. Look for the Injen cold air intake pre-filter, Injen Hydroshield black, and water repellent pre-filter for X-1022 and X-1050 filters when searching for this part.
Fitment is the first thing to confirm. This pre-filter is sized for an Injen X-1022 or X-1050 filter with a 6-1/2 inch base, 8 inch height, and 5-1/2 inch top, but the manufacturer's fitment and dimension listing for this exact SKU was not located during research, so verify the match against your filter before ordering. Installation is a matter of sliding the sleeve over the filter element, and no manufacturer install sheet was found, so inspect the fit and seating before the intake is reinstalled. Keep the pre-filter as a wearable item: when it clogs with dirt, replacing the sleeve is cheaper than replacing the filter.
No. The manufacturer says the hydrophobic treatment helps repel water but does not make the filter waterproof. Deep water submersion is outside what it is designed to handle.
The manufacturer offers a Limited Two-Year Warranty to the original purchaser against defects in material and workmanship on all Injen Hydroshields, and will replace a defective unit at no charge.
