It can come off.

Here's some information that has been posted before:

The best filter on the market is the one you presently have, the Donaldson PowerCore filter that GM puts in all LS3/LS7/LS9 Corvettes. Just find the best price for a replacement GM filter, and buy it. Flows all you need and filters the best.
The Donaldson filter you have is good for 50,000 miles, then spend $100 for a replacement element that is good for another 50,000 miles. If you do hit 100,000 miles you will have invested $100 if filter replacement and never, not once, had to take the time to clean and re-oil your filter. No oiled cotton gauze filter will last 50,000 miles without cleaning and re-oiling.
Will someone please explain to me how purchasing an oiled cotton gauze filter element for $125, or $300-$500 for a complete replacement air breather, and then purchasing the cleaner kit and oil for another $20, and then having to clean and oil the filter element every 5,000 miles, is cheaper then driving your car for 100,000 miles and only replacing the the Donaldson filter once.

And it's more than opinion, it's fact! Here is a copy of the venerable test report that presents the results of an ISO 5011 test of several air filters. The test was independently performed under controlled conditions using a $285,000 machine at Test and Corp of Rhode Island (manufacturer of the machine). Arlen Spicer, a GM Duramax Diesel owner/enthusiast organized the test. Ken an employee of Testand offered to perform the tests at no charge. (These tests typically cost approx $1700.00 per filter)
This is the point that K&N believers should pay attention to - Accumulative Gain:
"Accumulative Gain" is the total amount of dirt that passed through the filter during the test.

Having said that, if I were buying a used car and I checked this forum and saw that you used one of these high volume, low filtration filters, I wouldn't touch your car with a ten foot pole.
It has been proven again and again in oil analysis. The people who use aftermarket filters always show high silicon (dirt) levels indicating their air filter is not capturing all the dirt. As HOXXOH said >"You'd be hard pressed to find any aftermarket filter for the Vette that even attempts to claim equal filtration efficiency as the original Donaldson GM uses."<
Remember, the performance air filter companies are in business to sell you a product. Their claims, of horsepower and air filtration, must be viewed with skepticism.
