A must install if you have tweaked your engine as running above normal exhaust temperatures is a sure way to harm a motor.

I have fitted mine to a 300tdi Soft Dash Classic Range Rover so had to mount the gauge next to the A Pillar. The Softdash on a Classic is slightly different to a Discovery's dash.

A word of warning when removing the plate on the turbo is 'be very careful'. If one of the bolts snap it can be a pain to remove. I used a little heat and they came out easy enough. I used Stainless Steel bolts just in case it needs to be removed.

For the 12V feed to the gauge I used the ignition as my source as I didn't want the gauge on constantly. On a classic this is easily accessible under the drop down panel below the steering wheel.

Does exactly what it says on the packet, easy installation.

The product does what it is meant for. The Temp reading is clear and reactive. The installation is easy, but - unfortunately - I got no answer on my question upon the usefulness of the 5th pin on the digital reader. Together with the installations of a boost pin, a boost ring as well as a HP full size Intercooler my Defender 300 Tdi runs better by far with the same fuel consumption. The engine sounds less stressed, gives a deeper sound without any mechanical rattling in higher revs now. The Temp reading gives me the assurance of not overstressing the engine.
