During my long engine rebuild downtime, I thought I'd post what I am using for an "Air Hat" or plenum. I see others that are using the K&N Kit, but the hat it comes with is low and flat. This one and the set up came with the truck, and I have no complaints from the Original Owner's Install. Hood has no issues closing, even with the M1 2bbl. Thought this would be discontinued from K&N, but it is still available. I have not seen any other R/T use this. The piping looks Home Depot from the filter to the hat, and I just ordered a new K&N Air Filter (RE-0870)for this set-up, as the original is getting a little haggard looking.


K&N Custom Plenum
Cast aluminum plenum, beautifully finished with black powder coating and natural aluminum highlights. The plenum is designed to fit most American 4 barrel carb that have a 5-1/8" flange. Also will fit the Weber DGV carburetor when used with K&N adapter 85-1061. Designed for cold air intake, plenum has a single snorkel outlet that can be fitted with a 4" I.D. hose running to a remote air filter. A K&N universal filter with a 4" flange can also be clamped directly on the snorkel as well. See the Universal pages for filters that will fit onto the inlet. The outside diameter of the plenum is 9" and the snorkel sticks out 6" from the center of the plenum. Minimum clearance required above the carburetor flange is 3-1/8". Customer must provide 1/4"-20 hold down stud.
