Our dry panel design never needs oiling, which keeps your mass airflow sensor from being damaged by excess oil! This re-usable air filter is made from a synthetic fabric and not cotton. Cotton filters are made porous and must be oiled to trap dirt and debris. But that oil reduces air flow through the filter and it can become easily clogged. No oil = No fuss, no mess and improved performance! Easily cleaned with water .. This reusable synthetic air filter from Rugged Ridge fits 87-95 Jeep Wrangler YJ with 2.5 liter and 4.0L engines.
