H jerr,
Welcome to iRV2. There are after market air cleaners that advertise more mpg. If you Google "auto air cleaners" you'll get several choices. Some of these have been on the market for quite some time.

For me, I'll stick to what the engine manufacturer recommends.

I tend to agree with GaryKD about using a stock air filter. There might be a $300 to $500 annual fuel savings depending on miles traveled and mpg improvement but that would pale in comparison to rebuilding a 300 hp diesel engine because of grit ingestion.

If the aftermarket "improved" air cleaners would guarantee the same particulate filtering and air flow (in writing) then it could be just a simple cost justification. If not, I'll stick with the manufacturer recommended filters.

unsure it this is related or I may be hijacking the post

When I bought the 83 Pace Arrow it already had a Banks exhaust system installed including their air cleaner, and the PO made a point of using the special K&N cleaner / oil for it, can anyone tell me what is the difference with the Banks air cleaner and what may have came stock, just looking at it I can not tell the difference

ISO 5011 Duramax Air Filter Test Report is an ISO5011 test of air filters for a Duramax engine. I suspect the results would apply to any internal combustion engine. If more information is desired just run a search for " air filter test" and choose from the results.
