Thread: 300tdi Discovery airfilter indicator (Servisignal)

Fist of all, sorry about my poor English.

I seen Servisignal air filter blockage indicator in one Bobcat engine bay. I thought, this can be good option on my 96’ 300TDI Discovery.
The project was to install it for Disco Engine.

Found that this air filter indicator is available for Defender. Part No: NTC4611
Discovery 300Tdi air filter housing has a small pipe connection that can be good for indicator.

6mm Festo fitting +35mm 5mm fuelpipe
Mounted the servisignal with two 4mm rivnut and M4 bolts.

Hi Harry,

I have a more or less standard 96' 300TDi Disco (except winch, dual battery and night heater, and some electric mod.)
80% use on road, like a family car.
Here in Hungary the air is not too dusty, but filter indicator install was an idea.
Some picture about my car.
