I have a 2001 RT-10 and am thinking about getting the K&N filters and smooth tubes put on (I have the filters, just not installed yet). I was planning to put them on but then some people told me that it was a waste to remove the original filters since they are new, that the performance improvement is not noticeable and that it may actually be bad for the car if it goes over a puddle and ***** in water (or something to that effect). I am not exactly mechanically inclined and I am very careful with my car. Any thoughts on whether I should leave it as is (completely stock) or should I change the filter to the K&Ns
