Modifying TD5 Airbox

Ok..... if this 'modification' does reduce bottom end torque, what is the point of the exercise??

Is not bottom end torque on a diesel motor one of the advantages of having them in a 4WD.

I may have my black hat on, but what is the point of modifying something if it does nothing in the way of improving upon what aready exists ??
Why remove of this piece of pipe work which appears to have been engineered in for a reason?? As plumbing a pipe into the side of an air box, with nothing done internally, would have been the easy option in the first place.

I am no engineer but, you would have to ask, Why did they make like this in the first place??

Cheers,

Jason

This was exactly what I was thinking. It would have been much easier for LR to make it straight through so must be for a reason.

The reason the pipe extends into the air box is to reduce induction noise, but thats a moot point in a Defender isn't it.

The sucking from my snorkel head is noticeably more throaty after the mod.

The Td5 is pretty meagre in low down torque to begin with but I noticed no difference there and I'm towing everyday.

The biggest change I saw is all the crud on the air filter element used to be toward the outlet side, but now its spread more across the filter.
