Good Lord. An air filter costs as little as $4 and takes a whole 2-3 minutes to change. I change mine every other oil change, so about every 6000 miles. Why choke the life out of your engine and cripple your gas milage?
I installed a filter minder restriction gauge on my Vic. That way I can monitor the filters condition without removing it and introducing dust into the clean side. The filter has been in use for about 12000 miles and the gauge has not budged.
If its not creating restriction, how can it choke the life out of an engine, and kill gas mileage?
