I've had diesel trucks fitted with aftermarket air intake filters s&b is my go to and never have had an issue. Literally hundreds of thousands of miles put on running them, and since they're my bread and butter (I'm a mobile welding contractor) I feel confident in using them.
Thanks lemonturd
ah yes, because i love when people compare a frankly much more robust (by nature, ahem the nearly 3x size difference in displacement) to our smaller TDI's which have been built for totally different purposes.
wether you like it or not, the VW TDI's are built for fuel economy, and reliability. not for towing. also im not sure if you missed this fact, but VW built the TDI's and cummins built... well, cummins. because of this the 2 use different materials.
the material VW uses for their MAF coating on the PCB is easily corroded by oils. there are numerous documented cases of this!
now, regarding the "Literally hundreds of thousands of miles" comment, should we break out the psychology handbook and dig into why this logic isnt sound for justification? there is something called survivorship bias.
as
@PRY4SNO said, the airbox in your car is over engineered. it is a proper cold air intake, and will flow more air than your engine can use until you port + cam the head, or at the least upgrade the turbo.
thanks for the new signature
