I have just started to go down this path. The A/C that comes standard on the 08 SERK is NOT a high flow A/C - for that you need part no. 29260-08, which is the Screamin Eagle Stage 1 A/C. BUT... you also need part no 29121-07, which is an A/C cover which replaces the fancy CVO cover that comes with the bike. I don't know what it looks like, because there is no picture of it anywhere on H-D's website or literature, but I was told it was black with an orange trim ring. Sounds fugly.
I had my SERK in the shop today for Rinehart TDs, SERT, dyno tune, etc, and at 4:00pm I called and asked how they were going. They told me the pipes are all fitted and it looks fantastic, but the dyno had a crapped-out sensor, they had called the dyno tech in and he would fix it in the morning and they would have me outta there tomorrow afternoon. I questioned whether they would get all that done on a busy Saturday afternoon, but he assured me they would.
I told him that I read somewhere that it needed a different A/C cover than the one that came with the bike. He said no. I urged him to check, because I had a distinct recollection that a different cover was needed. He then called me back and said that I was right, and that they didn't have the part in stock, and no other dealers around had the part. I told him that I didn't want to ride the bike without an A/C cover so he then suggested that I pick up the bike and reschedule for another day. I then said "But you've got the Rineharts fitted and no custom map".
"Well," he said, "the Rineharts have been fitted to a different customer's bike and I made a mistake."
I hate being bullchitted. I don't mind mistakes. I don't mind an honest delay. But telling me I couldn't pick up my bike because the pipes were already fitted and then telling me he made a mistake - I'm now having second thoughts about getting the Rineharts fitted. $2,500 oughta buy sterling service, not BS.
Sorry for the rant, but if you can buy a hi flow K&N filter and keep the CVO A/C cover, I would definitely do that. I had a quick look at the K&N website, and when I searched specifically for the FLHRSE4, it said there was no product for it. The hits just keep on coming...
