Toyota Land Cruiser 3FE Desmog/EGR Delete Instructions

1988-1992 Toyota Land Cruisers with 3FE I6 4.0L Engine

The 3FE engine was designed with an EGR and SMOG pump. This was designed to reduce emissions on the vehicle. When offroading there is no need for either. You will free up a slight amount of HP and the smog pump and all needed accessories take up room under the hood. Helps your engine operate closer to peak performance and gets better MPG.
