Ok so recently I had bought the 9" K&N and installed it into my engine with the MAF pipe and whatnot, well my dumb ass drilled a hole into the MAF sensor when I installed it(trust me I have realized how dumb that was to do)and the thing broke. Well, I replaced the sensor but of course my dad took the car to goodyear to have it looked at. Well goodyear scared my dad into putting it back to stock when they told him that the filter was a danger to my car. The idiots said that they suck in water and can ruin the engine, and that the transmission fluid on the filter will ruin my MAF sensor. Now I know I could get the fluid off of the thing but my dad still is paranoid about the water thing. It is a daily driver, so what could I do to prevent water from going in the engine? I have looked at some of the cold air inductions systems but they are just soooo expensive, I would much rather put the extra money towards exhaust and whatnot. Please help, my car made a huge improvement with the cone and it really sucks with the 4" crap back in there.
