Fitted the K&N 57i yesterday. Sound is louder than I expected. Kinda curious to the sound from outside, might have to let a mate drive the car past me sometime.

Fitted it according the K&N instructions which puts it at the left rear of the engine bay when looking from the front. Getting air to it with the pipe supplied but not from down by the grill. Modified the standard air intake to take the pipe to the air filter. (Will try get a pic up later)
I'm thinking if rerouting the standard pipe from the engine to the filter so that the filter will take place front right. Only thing is no good connecting point for the K&N.
