DTs with a cone filter on the stock intake just sound TRAGIC, that typical low bellow the entire time, and it sounds jank... Haven't heard a HDI, but I'm going to assume they also sound jank, unless you've got a piece of 3" pipe going down to the turbo and a mahoosive filter on the end, they tend to just sound crap as it muffles out the compressor noise, but accentuates the typical induction drone...
Is that the HDi that is bad beyond the air filter?
Generally the MAF is a bottle neck really. A bigger one would improve flow.
As per the Td, the intake isn't really that hot on those. It's not bad by any means, but it's not as good as the HDi one I wouldn't say.
I always thought a wide scoop under the engine area firing into an enclosed cone right on the head of the compressor would be ideal on a Td hehe...
You WOULD need to avoid puddles though
