I did say that anything that gets through the filter won't hurt the engine. I was referencing the K&N filter based on what I do. I am saying the quantity that gets through the K&N filter using it that way is not a problem. Sure, to be very conservative, the greater the air is filtered the better the protection. As you know the more air into the engine the more fuel you can add and the result, assuming there is enough spark the more power you will make, to a point. I understand your position and respect it. Although Texas is not quite like your pictures and neither is NY. Rather than confuse the answer or scare the OP from doing anything. By the way, It a wonder anything runs at all in that cloud of dust, you must do great work. The OP is interested in better sound. The first thing I said was spend it on low restriction exhaust especially if he also looking performance gain. I am saying If it is going to hurt anything it is going to take a very long long time to do so. And that if OP wants to try it we need to offer our experience and study info that we think will steer him to the lowest restriction filter on the market, other than no filter or a filter we know doesn't filter at all. You and I both know that other than dirt track racers they suck the air in raw on extremely expensive engines that don't come apart because of dirty air. They say everything is bigger in Texas, obviously the dust is not. I say go for it OP!!!
