Cabin filter on G50?

[TellarHK]

Is there any form of filter for the cabin air on a '94 G50? Or has anyone found a way to add one?

Study HVAC drawings in FSM you will find the return air inlets above floorboard where a filter could be taped. Unfortunately there is not a viable way to filter the outside fresh air. You could tape a filter over cowl but it would get wet.

The Heater core and evaprator are already very dirty and block much of fan air flow, so you would need to clean them FIRST before adding a filter to avoid self destruction of fan motor from too much back pressure of existing restrictions. Any restriction slows down fan and increases it's current draw!

Damn, okay.

Guess there goes that idea, then. Thanks for the info.

That's the only solution I could conceive.

Here's a good DIY tutorial from Q45.org on cleaning of the G50 evaporator. While you've got it apart remove the blower fan and clean the blades to help extend the life of the blower motor and fan control amplifier.

It took the Infiniti engineers 7 years but they did finally put a cabin filter in the 97 and newer Q's.

Well, my roommate and I just did this... and now the air bag light keeps blinking. Any ideas, anyone?

EDIT: Started a new thread for this.
