I was wondering if anyone had any suggestions on whether i should buy a k&n performance air filter or an option short ram intake

 

I've went with all of the above ,
The K&N was nice for being cleanable

The short ram provided some gains but was fairly loud at all throttle levels.

I'd recomend the JCW intake , great gains and the flap is controlled by throttle so no noise at lower levels.

Great stuff, thanks

 

Injen makes great intake as well as KN
