I wish I had the pic from when my uncle put in the cool air intake on his 69 Chevy nova
I got to stand there and watch bc I was about 8 years old
It ran pretty fast after that.

About thirty years ago I put a Purolater Air Filter on my wife's car, and one on my car as well. A few months later wife's car started running rough. Took it to my Mechanic and he said the carb was stopped up and had something sucked down inside it.
Then I had a similar problem. The only thing I could think that they had in common were the filters. Shortly after this a coworker was complaining about his car being sluggish. I asked him, what brand Air Filer he was using. He answered, "Purolater" So I switched to FRAM and have used them ever since,
Since I responded I thought of my problem thirty years ago so I googled Purolator Filter.
Here is the response.
Purolator auto air filter problems often involve physical issues like collapsing or deformation, leading to restricted airflow, which causes poor engine performance (misfires, sluggishness, bad fuel economy) because the filter doesn't seal or maintain its shape like OEM or other brands. While some users praise their quality, others report premature collapse, potentially due to construction differences, affecting engine performance and potentially triggering check engine lights, making regular checks crucial, especially with cabin air filters too.
Common Problems & Symptoms
Collapsing Filter: Some users experience filters collapsing into the intake path, often reported in cartridge-style filters, reducing airflow significantly.
Poor Sealing: Gaskets or framing might deform, allowing unfiltered air to bypass the media, leading to engine dirt issues.
Restricted Airflow: A clogged or poorly fitting filter strains the engine, causing rough idling, hesitation, decreased power, poor gas mileage, or even a check engine light (e.g., P0171 code).

I went with a K&N engine air filter.
Ok, but why?

This K&N filter has made a slight but definitely noticable difference in performance
On an otherwise factory engine? No, it made no real difference. I run an S&B filter on my supercharged truck, every other vehicle gets an OEM paper filter because that is what's best in terms of performance and actual filtering capability. With an oiled media filter, that oil can transfer residue to the MAF sensor which will cause problems. Also, you have to properly wash and reoil that K&N (just like I do for the S&B) so you'll always have a filter that doesn't do quite the same job of capturing dirt ever again. My truck only gets driven a few thousand miles a year so the filter isn't much of an issue, but no way would I put that in my daily drivers.
