Today I took a Kaw filter in the Napa to get a cross. The Kaw filter was about $7.93. The Napa filter was about $7.45 for one filter. I was just about to walk off when he said if you buy 12 in a bubble pack the price will be $3.00 each Now the question is ....are these filters(NAPA ProSelect 21394) any good. If I look down into the center of the Kaw filter it has a spingy device and Napa doesn't. I definitely not going to use them in my big engines but was going to use them on the smaller engines.
