I've been meaning to share some of my favorite (low-buck) mods. Also hoping some of you will share some of yours as well.
This one involves "open" breathers,and their tendency to leak oil. Especially,when used in valve-covers without baffles. Carefully cut internal 3/8" pipe-threads inside the standard ¾" breather tube. Carefully so you don't scar yours up,like I did mine.
This will allow a (pipe-threaded) tube to be easily added. Not only does this move the opening considerably lower inside the valve-cover,any oil inside has a far greater chance to simply run back down the tube.
Another potential use of this by installing a brass reducer (with some JB-Weld as thread sealer to the breather tube) is to experiment with different size/shape pieces to reduce the flow of air travelling through the breather. To reduce air flow even more use allen-headed pipe plugs,and drill a hole through the bottom of the opening for the allen-wrench.

Another personal favorite is installing a cabin air-filter. Outside the cost of the filter(s) all it cost was a little of my time. The ductwork/vents get far less dusty,as does the cabin itself.
Attaching a slender steel rod inside the cowl near the center of the opening to the interior. A small thin horizontal piece of metal secures the top edge with spring tension supplied by the rod.
For the filter(s) I used Purolater C15388
This mod also prevents animal mischief in the blower motor area, which has been known to occur. Especially,cars that can sit for awhile.

The rod for the filter is already there?

I think this one came from under the dash on the passenger side,and I cut it to length. Mounted with a single screw. Works really well,easy to change filter w/o tools. I change it once a year,even though it wasn't terribly dirty this time. Some self-adhesive foam around the opening seals it up fairly well.

Works for closed breather systems too. What's under the cap of the breather is a chambered, baffled system as well that allows oil and blowby to drain straight back down into the crankcase for removal w/ routine oil change. PCV system is still 100% intact for gas flow in the proper direction and 100% closed for liquid flow in the unwanted direction.

Gotcha. Been pondering how to do something like that but haven't actually attempted.
