I assume reusable K&N filters still require that spray to capture the dirt more effectively. I found the K&N to be a high maintenance item that offers no gain under nearly all driving conditions. I am also concerned that the spray product may contaminate the sensor down-stream. That sensor is extremely sensitive to dirt. If so, your engine performance is compromised, and I think your Check Engine light goes on. You can clean the sensor, but I feel it is smarter to use a conventional air filter to avoid the condition.
My advise is to change the standard pleated paper filter every 10,000 miles under normal driving conditions. If you found yourself driving in a severe dust storm or a forest fire area, inspect the filter when you have passed the condition. If it is noticeably dirty, stop off at the next town and replace it.
We once drove our tiny little camper down into Monument valley on a windy day. The red dust ended up everywhere, all over the engine, and the air filter was a serious mess. That is one such situation where it was a-must to change the air filter after our visit.
Oh, and don't forget my reply on October 24th about inspecting the plastic flap that if installed improperly, will block a serious amount of engine air flow.
