Range Rover P38 # 073 - Plenum Air Filter and Engine Tuning

Winter is coming, and it's time to have a working plenum air filter to avoid snow and other debris to enter the cabin air intake system. The windscreen side trims, lower weather strip trim and wiper arms needs to be removed so that the plastic covers can come off to access the plenum air intake filter. Just take care now to break the weather strip on the side trims and save the clips where you can.

I'll also install a Ronbox Synergy 4 VP chip tuning device into the green P38. I have one in my black P38 already and there's quite a huge difference in response between the vehicles. The installation is quite straight forward. The only "hard part" is tapping into the fuel pump wires (2 of them). I prefer to do it at the engine ECM connector instead of the pump. The other connector is just a plug-and-play Y-connection at the MAP sensor which is at the fuel filter on the left side of the engine.
