Has anyone installed one of these? I know GM's have them. I was thinking it maybe a good way to tell you when its time to clean the AFE filter.

 

I have not installed on as of yet but I have used them on my diesel trucks. They did what they were supposes to and let me know when it was time to clean or replace the filter without having to undo everything to look at it. I went to slavage yard and got one off a ford superduty to install on my t100 for off road use.

 

they are nice but rarely work after a couple of months. You can pick up an in dash kit for $30 at most truck stops (looks like a gauge) or the at filter ones for $15
