finally got my K&N air filter in from O'Reilly's - took about a week but worth the wait. I decided to go with the "high performance" filter, #RC-2530, about $70. The only issue I had installing was that the support stud on the OEM filter was metric.... K&N being American made used a SAE thread on the stud. I hot a funny look at the hardware store asking for ONE 1/4-20 nut & lock washer! Owner gave me a freebie when he saw what it was for.... I also got a free sermon on the evils of the gol durn metric system!!! 😄
Along with the new Cooper Zeon tire on the back, and the ZZP header, muffler, and tune, adding a good filter to the CAI was the last performance mod I'll be making for awhile!
Really happy with the results!
