    I recall reading somewhere that an oil wet K&N filter could not be used on our HC's due to the type of intake air sensor. Can anyone advise?

    It's the same way with my Powerstroke turbo. Oil impregnated filters aren't the best choice for electronically controlled engines, especially forced induction.

    I don't even remember the brand off the top of my head, maybe AFE or S&B. It really doesn't matter, aftermarket filters are usually a waste of money as for performance gains. Stock or quality dry aftermarket filters will work fine. If you want an extra layer of cleaning effectiveness, get a filter sock.

    You can bet the stock filter on these HC's flows plenty of air and keeps the engine clean enough to last 100,000 miles or they wouldn't have picked it.

    I think that's true to an extent,, but there haven't been a car made that the manufacture has not left room for improvement, that's why the aftermarket company's are in business..I don't think the hellcat is any different,,, I know it's a step above the rest , and has been two years in the making, but I think the government made them detune it..

    Of course there's room for improvement and I'm absolutely sure they detuned it, probably to meet emissions requirements. All I was saying is that aftermarket air filters are usually a gimmick. Can they flow more air? Sometimes. Is it enough to make a difference? Rarely.

    Some people open up their air boxes and get more flow, but the HC's is pretty open already with the ram-air turn signal.

    Smaller pulley, maybe supercharger porting, larger supercharger, tuning, etc. That's where the real hp increases will come from.



    I meant 100,000 mile powertrain, not for a single air filter.

    I look forward to living vicariously through other Hellcat owners mods to see what this car is really capable of. However, I'd rarely have it at the track and more of a weekend cruiser for me. I'm planning on getting an extended lifetime warranty if I can and will not mod anything that will void the warranty. I'd prefer to bring it back to Dodge in 20 years when the Supercharger or Tranny craps out and have them take care of it. ;)

    Any one have a guess as to why they didn't use both inboard lights to feed the supercharger? Maybe the piping wasn't going to work under the hood, but it seems like they could have gotten close to twice the available air flow.

    The supercharger is designed to pull in "X" amount of air, obviously the one intake provided more than enough volume for the required air to flow
    It might have looked "cooler" to have 2 inlets, but there would not have been any advantage

    It actually would be a disadvantage to add more drag on an already boxy front end. The necessary cooling and intake requirements were met, so no gain would be realized by adding more "air-trapping" areas to the nose.

    Well, I thought I'd get the K&N and AEM filter (dry flow) and have a look. Just holding them up the sun you can see so much light through the K&N and the OEM over the AEM. Well I've had the K&N in for 200 miles and the SC whine is louder and gas mileage went up 18mpg around town and I swear it feels quicker if that is possible. ;) I've noted no issues. Will continue to run it and report back.

    Awesome.. when I put a K&N CAI in my Lightning the supercharger got a LOT louder (was pretty quiet stock). Hellcat is already pretty loud, can't imagine any louder. What is the K&N part number? I'll have to pick one up.
