When to replace a reusable air filter in a superduty truck?
I've had mine for 8 1/2 years. At what point do you replace it? It just feels like I need to clean it more often, like it's not performing like it did in the beginning.
If it's a diesel, I would throw it away and use a stock filter. On the 6.0's, the stock one is good up to about 500 hp and filters better than any aftermarket one.
