K & N Filters

K&N air filters

This test seems to me was all about boosting the AC Delco
brand and knocking down the K&N brand.

Plus there are no reports on who did the testing
it says that it was unbiased. However, most legit tests will
post some semblance of who they are.

Dont believe everything you read - I think K&N are good
filters for most driving conditions (at the very least).

I ordered a K&N from RN way back in 02 for my 91 Disco V8. It too made a huge improvment in MPG and HP. Plus taking the horn off made the incoming air make a lot more noise and sounded cool!

Best bet is to use the K&N for every day driving and change it out with a paper filter for dusty trails.

Or even better get a precleaner wrap for it, if it will fit in the air box.

As stated before a snorkle will help to get it up out of the dust, maybe even a 2nd filter on top to pre-filter it.

I dont have to worry too much about dust here, but in Uganda 90% of the roads were muram (packed red clay) and got quite dusty in the dry season. I checked my filter often but didnt see any caking of red mud on it or any in the air tube either. Hopefully for the guy who bought it off me the cylinders didnt get scored too badly if dust did get by.

From the link
" This report presents the results of an ISO 5011 test of several air filters designed for the GM Duramax Diesel. The test was independently performed under controlled conditions using a $285,000 machine at Testand Corp of Rhode Island (manufacturer of the machine). Arlen Spicer, a GM Duramax Diesel owner/enthusiast organized the test. Ken an employee of Testand offered to perform the tests at no charge. (These tests typically cost approx $1700.00 per filter). Ken, also a Diesel enthusiast and owner of a Ford Power Stroke Diesel, shared Arlen’s interest in performing an accurate unbiased test of different types and brands of diesel engine air filters. The filters used in the test were purchased retail and donated by Arlen and other individual Duramax Diesel owners. The detailed reports from the test have been compiled and are presented in the following pages. The final pages of this report present the interesting story how and why Arlen organized the test"
