    Does anyone know what purpose the wire mesh screen ring that your air filter fits around does? It seems that all it does is restrict the air flow. what would happen if you took it off?

    I'm guessing that it holds the filter paper in place so it doesn't get sucked down your intake. [​IMG]

    Take it off. Its a charcoal filter and all it does is restrict.

    your truck would blow up... ;) lol just kidding. I ditched the whole breather assembly and went for an open element one. I believe that the screen you are referring to is some sort of flame arrestor.

    It's just another little piece of power-robbing emissions equipment. Take it OFF!!!!! The base is glued to the air cleaner- I used a heat gun to soften the glue and peeled her off.

    it keeps big [censored] from penetrating the filter, as long as you dont take any darts through the intake youll be fine

    Where is this screen located? I thought you were talking about the screen that's actually part of the filter element. My K5 uses a filter canister from a 80-something GTA Trans Am, so the stock '75 filter is long gone. But I don't recall any kind of screen in it, or on my '87 K5, '91 S-10 or '94 Suburban. Where is it??? [​IMG]

    It's located right behind the air filter and is about the same size as the air filter, but has a smaller diameter.

    I'd have to agree with CrazeeBush and say it's a flame arrestor. Those were the last carb years, and with all the stupid emissions-related crap on those carbs, it wouldn't surprise me if a backfire or two ocurred and scorched a filter or two, prompting a knee-jerk reaction from GM to put another piece of crap on the motor.

    I was working on a friends j**p, and he has fuel injection so the air filter was at the grill on the driverside of the vehicle. Well anyway I took off the airfilter because it was pretty grimie, and what do you know.... He had peanuts laying in the bottome of the case. Not normal peanuts. I'm talking honey roasted [​IMG]. I said "Why the heck are there peanuts under your airfilter?" We still don't know how they got their. Kinda off subject but thought it was funny!!
