stock filtration vs aftermarket?

[AaronATX]

hey,

i am asking about this for a buddy of mine. does anyone have the specs on the stock 6.4 air filter filtration, vs the banks intake?

Unless he is doing a DPF delete with a Spartan/SCT tuner he doesnt really need to fool with a cold air intake. If he is just doing a drop in filter for the stock air box, then I am sure that the Banks is a little better than the stock. Someone else with chime in on that. But as far as the intake, he will most likely get a code all the time with an aftermarket intake and the DPF is still on the truck

[AaronATX]

yeah we both know that, he got it as a gift and figures he might as well put it on, unless someone has a good reason not to, such as poor filtration.

I would assume that it probably does filter better than the stock. Banks makes a pretty good intake.

[po-po 5.0]

Probably filters ~95% as good as stock, with about 5% more flow than stock.

as far as warranty goes, he got a CEL from it (probably MAF sensor), and took it into the shop to have it checked out and they are now trying to void his warranty because of the intake. he also has a filter-back magnaflow and they are trying to void him for that too. i thought under the magnusson-moss act they can't void the whole truck's warranty because of something like that, i.e. if the lights stop working they can't waive the warranty on it because he has an aftermarket intake, etc. can someone clear this up for us? we've been on google all day and can't find a direct answer.

I would raise hell about both. The DPF back Magnaflow is perfectly fine. It has the vents on the tip of the exhaust and it designed to work with the 6.4 with the DPF still on. He should not have taken the truck in for the CEL though. All cold air intakes with the exception of the S&B will throw a code while the truck is stock. It actually will throw a code that has to do with the DPF as well, it is weird. But I would be up there giving that dealership hell and ask them what reason they have for voiding the warranty. Neither one of those aftermarket parts will affect anything else on the truck. My dealership is cool with my truck, so I dont know how to really deal with it other than make them prove how what is done is damaging the truck.

Tell him to go to another dealer! I have a sct dpf delete and im getting a whole new engine because a injector stuck open and burned a hole in a piston. Tell him to go get his truck and never talk to them agin. He should go talk to a salesperson and ask if they are a tuner friendly dealer

To answer the original question, I'm pretty sure banks uses a K&n filter, which suck. And by suck i mean let more dirt into the engine.

Why would banks use a K&N filter?? Im not saying your wrong or anything, just curious as to why a company like the almighty Gale Banks has would use an inferior filter for their intakes. I am *not* a Banks fan by any means, but I have always heard pretty good things about ther cold air intakes.
