Consider nugget ducting upgrade first up, before hacking into the CAT IMHO.

Absolutely agree that fixing the stock air intake ducting to open up the airway and let the engine breathe better ought to be a priority. I remember back when I did the BAS 170hp tune the advice from Pete Bell was, at the least, make some mods to the airbox itself to allow freer breathing.

I tell people I have a V8, 2 door convertible - and then roll up in my 101. [emoji4]

As already mentioned a snorkel will be worse for performance.

Worst thing for an engine is turbulent air, an engine wants passive dense air, of course that is all a bit redundant with a turbo engine.

The Nugget Stuff intake is an awesome bit of gear as it seals and water proofs the intake from the snorkel.

But its a different thing, its not a performance mod.

Not sure of that myself - Given the weird narrow odd shaped stock ducting. A good, unobstructed, near straight bit of 90mm silicone hose may well encourage a few more neddies to pull harder.

Neddies haha!!

I was shocked when I pulled the stock ducting, compare that with the straight piping it has to help the 170 odd(give or take) fine BAS bred ponies I reckon. I did also remove(widen) the internal section off the air box past the dust separator for good measure.

For full disclosure I do not receive any kickback from Nugget (only emails talking about new goodies).

I swear by my Hiclone,it gives me 30% more power with a 40% reduction in consumption. Pat

Wait until your polariser arrives, combined with rare earth fuel magnets it’s unbeatable.

I did the same mod inside the air box, and removed that little propellery dust separator thing as well.

Tdi's and TD5's had a ridiculously restrictive intake duct between the inlet grilleon the guard or Snorkel and respective air cleaners. It stepped down to 50mm at the water dump, and a Safari snorkel was only about 50mm ID at the point it met the intake duct.

On my old Tdi I replaced the entire intake duct with with 75-80mm industrial hose and cut the end off the snorkel at a point it was 75+mm OD.
The Land Rover setup really offended me! [biggrin]
