We have a new MAF kit for the Toyota Land Cruiser. It makes acceleration much smoother and effortless. This is a really nice upgrade for these 4.0L engines.
Here is the engine before installation of the MAF kit.
This is what it looks like after installation of the kit. The stock air inlet and air filter enclosure are retained.
All of the stock hose and vacuum line connections are preserved. Connection of the hoses is done with an aluminum adapter that we have fabricated specifically for this application.
Here is a comparison of the inlets of the stock air flow meter vs. the MAF 3.0 sensor that replaces it. Note the multiple sharp right angles internal to the air flow meter. By comparison, the MAF sensor has a much larger cross section and is a lot smoother.
This photo compares the old and new transitions that feed the air flow meter and MAF sensor respectively. The silicone elbow in the MAF kit has a 4 inch diameter and is far less restrictive.
The wire connections are completed with a custom wire harness for this application. This photo shows the connectors for the new MAF sensor and the IAT sensor that are used.
Wire connections to the engine harness are completed a few inches from the ECU. The ECU is mounted to the roof of the glove box. Complete instructions accompany the kit which detail the wire colors and pin numbers needed to make the required connections. This photo shows what it looks like after the wire connections are completed.
The Toyota Land Cruiser is a rugged, solidly built vehicle that is fun to own and drive. Unfortunately that heavy duty construction makes the vehicle weigh 4597 lbs. That is a lot for the stock 4.0L engine to move around. This MAF conversion really helps. After installing this kit you will feel the improvement the first time you press the accelerator.
