Im about to start tuning the and i cant decide on an induction kit. What are peoples opinions on the following:

Powertec SL1
Pipercross kit
K&N 57i

I voted Pipercross.
Viper though as you need a proper cold feed else you'll just be sucking the air from inside the engine bay which'll make it worse.
Though anything has got to be better than the standard airbox which sits on top of an extremely hot engine!!
Put your hand on top of your airbox after a journey and you'll see what I mean!!

The viper is mega bucks tho isnt it, is it really that different?

Apparently mid range torque is fantastic with one of these.
Which is where you spend most of your time in the real world, not up at the red line
