Air filter question

[olds307 and 403]

That is false advertising that the open element gives you increased airflow and performance. My air/fuel mixture gauge told me that when I switched from an air cleaner like above to a Gm duel snorkel. The duel snorkel drew in more air than the open element.

I figured as much. The dual snorkel's go for stupid money, even used. I made one from a 260 and 307 air cleaner, it looks a lot like the 307 HO version.

If you have a 4 barrel that will fit

Make sure it has a drop base

A drop base for a 3" element? Mine fits on my Qjet with room to spare.
