Series Air filter upgrade

[cedryck]

Does anyone know if K&N make a series truck air filter replacement for the Oil Bath? Are there any other makes that do the same? Any modifications needed to your carb. after doing so?

K&N air filters are not good at filtering air. Oil bath air filters are far superior IMHO.

[cedryck]

Could not agree more with you. That is why I have been running an oil bath for the 7500 miles that my series 2a has been on the road. But, I am looking to get a little more breathing from the engine, and considered dumping the filter, I have a stock exhaust and do not know how much more umph it will add. Perhaps I will just stay with what I have.

"Umph" and a 2.25 are incompatible. That's just the way it is.

Good one Safe Air one. I am well aware of the slowness, time stops factor of series driving. I think I will keep it as is, plus I love the vintage look when you show someone your engine.

I have used K+N filters on many vehicles and find they filter well and improve air flow. You must clean them more frequently if they are used off road in very dirty conditions, but this is easy. If severe conditions are anticipated, put the oil bath back on temporarily, easy. Every car or truck I have put a K+N on has had a noticeable improvement in performance, even the 2.25. This is especially true if you are using a carb that increases intake volume.

I have a K&N on my SIII. There was a noticeable improvement in top speed and acceleration when I ditched the oil bath. Mine wasn't for any particular application. I just looked through the K&N catalog until I found one with the right inlet diameter and height.

I went OEM and ordered a snorkel and oil bath to replace my filter element. The regular oil bath really restricts airflow where as the snorkel lets more air in with the high quality filtration we expect.

What model did you purchase?

Fuzzy math?

The snorkel tubing and elbows add even more restriction.
