Comparing air filters

[Ratau]

Did anybody tested air filters like Uni Foam, K&N and Armsoil on 6.2 diesels and if so is the results known or published?

Jim Bigley has done an objective comparative test and found the Amsoil Foam to be the best at trapping dirt. Check thru the tables of contents for the yearly reprint books to find when and where this was published. Anecdotal evidence from several members supports this finding.
