Kilby Enterprises Kilby On Board Air for 91-98 Jeep Wrangler YJ & TJ with AC and 4.0L/2.5L

Depending on your vehicle and it's specs, you may or may not have to trim the inner fender to clear the York compressor. On TJ's, you will need to remove the factory air cleaner and replace it with a K&N P/N RU-0960 or equivalent filter and air tube setup. The core support rod above the factory AC compressor may need to be bent to clear the compressor fittings. 2.5 TJ owners will need a 1" motor mount lift in order to get the compressor to clear the shock tower.
