    Intake Issues

    After deleting my 2018 Cummins I decided to put on a S&B cold air intake. Truck ran great before intake install, had no power and very sluggish after install.

    I checked wiring no less than 4 times all seemed fine as far as that goes, good connections on all sensors.

    Took intake off and put stock intake with K&N filter back in and it ran great again. I don't get it!

    Sending this thing back to Summit for a refund not messing around with it any more.

    Anyone ever have an issue with these intakes?

    I have seen different response for each item sold, depends on vehicle and use.

    I have the S&B and nothing changed. Others got a taste of increase in mpg's, and like you, others were negative.

    Glad you could return it.

    Stock air-box is one of the best engineered pieces provided stock.

    It flows way more than the motor needs.

    Is the K&N dry filter?

    The K&N is one you spray the oil on after cleaning it.

    @DRD wouldn't he need to be retuned for the new intake?

    Re: Intake Issues

    Ray said the tuning is not changed when using an S&B intake vs the stock intake.

    I was going to get a new MAS and try it but @ 200.00 and special order thru parts house I decided to put the stock set up back on and try it.

    Glad I did because the truck went back to running great again.

    I know tons of people use these without issue but my issue was real for sure.

    Yes this one was a mystery to me. Tuning is the same for a S&B intake vs a stock intake.

    Also we have many customers running S&B intakes with no issues, so again I'm baffled.

    Re: Intake Issues

    If you don't mind me asking, how do you like the K&N filter?

    Have you experienced any type of "dust" getting by?

    Have you checked the intake tube right before the turbo?

    I've had great success with a completely open K&N filter on other off-road vehicles that see conditions that are considerably more dirty than this on road rig.

    I'd really like to put my K&N back in just haven't heard if they will filter the air as required.

    I'm eager to hear your experience.
