Hi-Capacity air box 97 & up question

[jggiedeman]

Hi all,

I'm looking to install the K47 hi capacity air box on my 94 K2500. the old box was done in. I can get pretty good prices from salvage yards but did every 6.5 after late 97 come with the K47 hi capacity air box? Thanks,

Not sure of your part number K47 reference. The filter element is roundish for all after 97 I believe but I think there is a BIGGER element for gasser trucks special that may be high capacity. As opposed to a flat panel filter for earlier models. I THINK the 6.5 turbo came only with one box.

My '97 box has a sticker on it 48 use filter element A1300C and raised lettering on box cover stating same filter too. Also says use A1306C for extreme dusty conditions.

I think the K47 is probably in reference to an RPO code.

As long as you get the round style box, you're good.

Thanks for the replies. I found a complete '99 air box, fender to turbo for $75 on www.car-part.com. Should have it by Fri evening. I'll let you know how the install goes when the rest of engine rebuild begins 3-4 weeks from now.
