We have all seen this before but I thought I would share how I did mine.
I took a piece of 3" round al. stock, cut a 1" section then faced both sides on my old lathe. After drilling a hole in it I took the rest of the material out with my homemade boreing bar to fit the intake pipe. A little Loc Tite, install air filter and tighten clamp and presto ---Hot Rod air cleaner !
Think I'll get the 5 to 10 horsepower increase they advertise
LOL
