6-7/16” and 9” Round Air Cleaners

O’Brien Truckers’ line of nostalgic cast aluminum air cleaners now includes the round finned style you see here, in 9”, and 6-7/16" diameters.  These are very reminiscent of the old Cal Custom-style air cleaners from the 50’s and 60's, except with heavier, more traditional fins, which you can paint as shown (shipped unpainted).
The 9" comes with a cast aluminum base.  Both are for 4-barrel applications with a 5 1/8" opening.
The 6 7/16" smallest size in the foreground is especially versatile, can be ordered with your choice of no less than 5 different cast aluminum (not plastic) bases.  It can accommodate a 2-5/16" diameter 1-bbl, 2-5/8" and 3-1/8" 2-bbl, and 4-7/32” and 5-1/8" 4-bbl carburetor necks. 
Because it’s one of the smallest 4-barrel air cleaners to be found anywhere, it provides added clearance for extra-tight dual quad applications.  All three of these air cleaners come with washable cotton gauze “lifetime” filters.

We are the founders of O’Brien Truckers which we started in 1978 by offering the “No Club Lone Wolf” car club plaque which led to custom made plaques, belt buckles and finned aluminum engine accessories and hot rod parts. 
The very first item Dennis produced was a “No Club Lone Wolf” (NCLW) car club plaque which I made by pouring aluminum out of a small pot in our old barn in North Grafton, Massachusetts to make my first NCLW plaque.  Even to this day, it is still a top selling plaque from our stock plaques & toppers.  Presently, we now sell an entire line of NCLW items:  T-shirts, sweatshirts, satin embroidered jackets, hats, hat pins, key chains, belt buckles, small plaques, toppers, lake pipe caps, ornaments, and wind-chimes.
