Rugged Ridge's constructs this round filter for your 4.2L YJ out of synthetic fabric. This filter offers a number of benefits beyond the usual factory original equipment.
The biggest difference between wet filters and this Rugged Ridge dry filter is the maintenance. Wet filters require cleaning, and a long drying period, and re-oiling. This dry filter from Rugged Ridge gives you maximum airflow and superior filtration, and requires much less labor to maintain and keep working properly. Simply wash it with water and let it dry. The lack of oil also keeps the MAF sensor safe by eliminating the risk of over oiling.
The filter is backed by a 5 year limited warranty for your added peace of mind.
This Rugged Ridge Reusable Round Synthetic Air Filter is designed to fit on the 1987 - 1990 Wrangler YJ models with the 4.2L engine.
