K&N filters

Warp9.9 is that cover over the KN filters a cover for the rain?
You have the RX 4040 as well I'm thinking of getting bigger K&N filters would it make a noticable difference if I slept up to the 1717's? Or will it not be too noticable and just go with the RX4040 performance?
 
I do not think you gain much on the 1717 they are taller but small in diameter then the 4040 not much but then the 4040 has filter area on the top where the 1717's do not.

Oh and the over flow was bought at a local hot rod store it came with the small wrap around clamp the rest I machined
 
Cool thanks watp9.9 so I got the smaller K&N filters not sure of size but if I go to the RX / 4040 I would notice the difference?
 
Yes the Ramair is far superior to the small three K&N 2780 the only thing K&N's let flow better are the K&N RX 4040-1's
 
4040 are bigger than 1770's
