Universal Air Cleaner Assembly - Parametric

I drive a 1971 VW Beetle and I did some upgrades to its engine. One of the premises I wanted for the upgraded engine was that the looks would have to be as stock as possible.

So, for air cleaner, I got some VW Brasília dual-carburetor air cleaner assemblies (which use Fram CA3130 paper filters as standard) and replaced the filter with a high flow compatible one that was supposed to be plug-and play.

However, the "stock" (aftermarket) air cleaner pan was quite restrictive due to some structural mounting points that covered about 45% of the intake tube, killing the airflow to the carburators and choking the engine in the proccess.

I did put some "sporty" conic air filters provisionally but the looks of that didn´t please me. So I went to the drawing board and designed an air cleaner assembly that did not have the sections that restrict airflow.

It´s still a work in progress, though. Will update this as long as possible. It´s still on test runs, so far it´s working good. I mig
