I have a 2001 SLS I just recently purchased and have fallen in love with it. So, now I think it's time to give my new baby some TLC. Has anybody out there put a K&N air filter in thier SLS? If so, what is a good kit? Did you see a 10 HP increase as exspected? Also, i want to boost the HP without jumping out of the factory exhaust. Any suggestions other than N2O? 
Yes, the STS would have been my HP preferance but a physical condition requires the ride of the SLS. I would love to tweek this SLS to give the performance of a STS.
