Cars Q&A

Hello everyone, I own a Yamaha Fazer'09 model since, Aug.I am planning to gift my bike an upgrade of K&N air filter. I've seen two variants for the same, namely RC1060 and R1100. My concerns: 1. Which one would suit the best for my bike (153cc)? 2. Will this air-filter be really increasing my bike's performance(Power and Mileage)? 3. The prices as per Reliance Auto Zone, Bangalore(Teacher's colony, nr HSR Layout) are : RC 1060- Rs1690 R 1100- Rs2000. Can I get prices competitive to this anywhere else in Bangalore?
