The Injen 1052BLK is a black Hydroshield water-repellant pre-filter sized to fit over the Injen X-1045 air filter, which measures 6-1/2 in at the base, 5 in tall, and 5-1/4 in at the top. Injen describes the Hydroshield line as a filter treated with a hydrophobic coating that helps repel water, and the company notes that the treatment does not make the filter waterproof. Compared with running a bare intake filter, this outer sleeve gives rain, road spray, and mud a first barrier, so the filter stays cleaner for longer.
Injen says that shielding the filter from contaminants can translate into more power and extends the service life of the filter. For a buyer building a rain-season or high-water-crossing setup, that is the real case for paying for the Hydroshield rather than relying on the filter alone. Searches for "Injen X-1045 pre-filter," "Hydroshield 1052BLK," and "water repellant cold air intake pre-filter" typically lead to this exact size, so confirm the filter number before ordering. The manufacturer backs Hydroshields against defects in material and workmanship, though the warranty term has been listed differently across models, so confirm current terms with the manufacturer.
No. The manufacturer describes the hydrophobic treatment as a way to help repel water, and states that it does not make the filter waterproof. Heavy water crossings can still saturate the filter, so keep the intake and filter checked after deep puddle driving.
Yes. The 1052BLK is sized for the Injen X-1045 filter. The manufacturer lists Hydroshields by the filter model they are confirmed to fit, so verify the X-1045 number on your existing filter before ordering.
The pre-filter is a slip-on accessory, so the job is typically a quick filter removal and reinstall rather than an intake modification. Remove the intake clamp, pull the filter from the intake tube, slide the Hydroshield over the filter so it seats snugly around the base and body, and reinstall the filter. Check that the sleeve sits flat and does not interfere with the filter's rubber flange or the intake's mounting points. Installation steps were not confirmed against a manufacturer install sheet, so follow your intake's own instructions where they differ.
