TTS were doing them for £170 delivered. Waste of money in my opinion - lots more air filters of as good quality for that price.
 
The dynatwist maybe hot, but it should be ducting the cold air in, so if the shield is hot, then its doing its job.

hope its doing its job, i gets pretty hot!! going to maybe get a mk2 golf bumper intake and modify it too fit in the small intake under the fog light on my front bumper, has this been done before??
