I am interested in buying an AFE intake system for my 04. 5/600 but am concerned about warrantee issues should something go wrong with the motor. Can anyone tell me with absolute certainty that DC will back their product with AFE intake systems installed? I have already asked my dealer about it but they are holding the paty line... "any modifications to the engine blah blah blah... ... " I would accept that stance but there was NO conviction in their position and I'm not even sure they understood what the product was. I would think that DC would recoginze that an engine mod such as an AFE intake system is non-invasive and passive; allowing more clean air into an air pump to produce more power and better mileage is a good thing.
