Just recieved my smooth tube and filters from K & N. Very nice parts, plan on putting them on the car and going to the dyno with the Ilonis region next month. Check with your local K & N parts supplier for pricing. The K & N part number is 63-1090. Direct replacement of the tube and filters looks like it should fit nicely into the air box. These were designed and built specifically for the SRT10. Will try to get some pictures to post when the car comes back from Autoform in two weeks.
