Great look and great performance. I believe these are usually used for motorcycles but I have them on Dual Side Draft Carbs. They give the engine a great look while offering optimal perfomance. Thanks K&N...!

The 2340 filter works perfect on my 2009 Aprilia Mana and I must of shed about 5 lbs from removing the OEM airbox system. To be safe from the rain, I added the 22-8028PK - Air Filter Wrap on it just in case.
