| Any thoughts on Baldwin oil filters? I still have a few from my 328 days I never used....

This is correct from research I did several years ago. I take a hard pass on K&N air filters. At the time I was digging, the AC Delco air filters seemed to perform best. Decent air flow when new, good filtration and less of a drop in flow as they got dirty.
Oil filters are a different story and are constantly evolving. Mobil 1, Bosch Extended Performance and Royal Purple are all pretty good with RP probably being the best.
For oils I have long been a big fan of Redline.
I recall in testing I was involved in on BMW M30 6 cylinder engines the K&N drop is filters were awful in every respect. They had a fraction of the surface area of the MANN or other OEM equivalent and once they got a bit dirty restricted airflow to the point where the engine would stumble on part throttle acceleration. They were great when clean as far as airflow but the reduced area made the inefficient once they got slightly dirty and on a street engine, I would rather have the filtration over a few CFM of airflow and have to clean the filter every month.

Hmmm
Had to read this twice – how could an oil filter make a HP difference?
Ahhh – K&N “air” and oiled air filter. OK
Do you think it caught more dirt? Make the engine last longer?
Just wondering . . .

When I had my 85 with factory exhaust on a dyno in the late 90s the RWHP was around 190. FYI - I was testing out KN oil air filters vs Fram paper filters and found KN decreased HP by approximately 5hp…..
