better breathing
I rebuilt my 300Tdi a year ago with a Turners Performance head and a VGT from Bell Auto Services. Performance was much improved and it was lovely to drive but I could help feeling the engine was a little restircted.

After my sucessful improvements with the new stainless steel striaght through exhaust I turned my attention to improving the intake. After reading the thread on modifying the intake box on Puma's and Ian's 102mm intake pipe mod I was convinced I needed to come up with something to improve the breathing on my 300Tdi.

After a bit of searching I have found this air box from ITG. It is a lovely high quality aluminum air box with an ITG foam filter inside.

It fits the standard 300Tdi mountings although I did line the inside of the straps with some self adhesive foam to protect the air box and give a snug fit for it.

It has a 102mm induction trumpet so I can run a cold air feed to it.

It gives lovely free breathing and still nice and quiet. Really pleased with this mod.

With the Puma there has been much discussion and debate about filters, contamination of MAF and various other niggles. I too have an ITG filter but a standard fit one that sits in the OEM box. Nice bit of kit and one that has not given me any hassle.

Thumbs Up

Have to say that is a beautiful looking 300... Wonder how it compares to the HS 2.8L TGV version of the 300...!??!

I looked at the 2.8 TGV before deciding to rebuild the 300 with a few improvements.

When it comes time to get a new engine/rebuild again I think I will be speaking to IRB about their blueprinted 300Tdi unit.

A 2.8 is tempting but with production ended I have a concern about spares etc. From what I have heard it is a good unit though.

Would be interesting to see with a cold air feed connected to a snorkel.

Yep - I did a test with my Puma, comparing taking air from outside with inside the engine compartment - pretty horrifying results under certain conditions (amazing how quickly the temperature in the engine compartment changes). Tell someone you love them today because life is short.
But shout it at them in German because life is also terrifying and confusing...

Alex - looks good.

I had a one of the prototypes of this - just never got round to fitting it/doing a kit.

I would get a cold air feed to it though... at the moment you will be sucking in warm air.

Don't look the best in my opinion - and the scoop is the wrong way round...

A forward scoop is ideal to force air into a top mounted intercooler - but a forward facing scoop feeding straight into the underbonnet area messes up under bonnet air pressure and can reduce air flow though the intercooler and/radiator. IRB

So LR's design of sucking air through the wing side isn't so bad then Wink Tell someone you love them today because life is short.

Thanks for the comments guys.

Gmack - the header tank is an Allmakes one that I bought. I think anywhere that supplies AllMakes should be able to sell you one. I think it was £20.

Ian - I may need to get one of those 102mm air intakes that fir the side vent that you have.
