Upgrade the air filter in your 2020-2022 Jeep Wrangler JL 3.0L EcoDiesel with a new Drop-In Air Filter. The air filter in your vehicle serves as the first line of protection against harmful airborne debris that can damage your engine. Factory-style drop-in air filters typically feature a paper filter media, while aftermarket performance filters use an oiled cotton-gauze media, or a synthetic dry media. Drop-in air filters get their name from their designn as most have a "drop-in" installation and simply fit inside the factory air box. Find drop-in filters from manufacturers like S&B Filters, AFE, K&N Engineering, and others at XDP.
