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?
