If you install it properly, the new intake tube will actually protect the engine, not damage it. However, as I mentioned in the Buyer’s Guide, oiled filters are known to slightly decrease the powertrain’s potential. That’s because they tend to use flow restriction to successfully “battle” contaminants, which results in performance drawbacks. Also, most vehicles from dealerships have built-in computers that control pretty much everything.
And when they detect an increased airflow, they might deliberately change the ignition timing and implement restrictions for the engine. This mostly concerns newer cars, especially crossovers and sedans. So, if you’ve got a rough-tough Jeep, especially the 2nd or the 3rd gen, you won’t have to worry about any of that.
