I was at Racetorque today and I was asking about the silicone intakes that they have there as I need one soon. They reckon that you dont need to take off the manifold to get the new one in. Yes it is a bit fiddly but can be done. They also advised that I get the car re tuned due to the increase in air flow to the turbo with the new intake which will effect the boost. I have Ecutek on my car.
