The Injen Hydroshield Water-Repellent Pre-Filter fits the X-1051 air filter and is sized for a 6.5-inch base, 7-inch tall and 4.5-inch top. Treated with a hydrophobic coating and UV resistant, it helps divert contaminants and repel water to extend filter service intervals and protect peak airflow. It’s puncture resistant, reduces servicing frequency and is confirmed to fit specified Injen filters; it does not make the filter fully waterproof.
