Need a heavy-duty air intake elbow for a big diesel?

This is for a Cummins 15-liter ISX or QSX engine, but it fits a whole lot more.

The OEM part numbers are 3682674 and 3681017.

It's a 3-inch to 4-inch elbow tube for the air intake connection.

BLKPRO (BLK Diesel) makes this one.

And look, this thing fits a massive list of vehicles and equipment—we're talking Kenworth, Peterbilt, Freightliner, International trucks, plus ag equipment like John Deere and Massey Ferguson combines, industrial stuff like CAT loaders and Hyster forklifts, and even marine and genset applications.

If you've got a Cummins B, C, N, or M series, or anything with an ISX or QSX, this might be the hose you need.

It's brand new, ready for your project.
