Who is running a restriction gauge?

My Sierra Denali pickup has one standard with it's high capacity filter (optional on other models).This is all OEM from the factory and I've never really been able to read the thing. I think I will go out and figure it out now, Lol!

if you are looking for one of these the cheapest one i could find is here:

like someone else said, if it saves you from needlessly replacing an air filter it has already paid for itself. not to mention you are helping to protect your engine even better by leaving the air box alone and that old filter in there for as long as possible

you can put them anywhere on the engine side of the air box, basically the side of the air box where the air has already passed through the air filter. they are very easy to install, just make sure you will have room in your engine bay first.
