Still trying to improve air flow and path on my D1. I have a snorkel and square type filter housing. I’ve looked at powercore from donaldson and fleet guard similar. They are all too hard to fit and large.

I’ve read the filter thread from isuzurover (thanks) and he stated that the cylinder filter box has better flow than the square ones.

The cylinder housing might work for me. Do they provide better flow and anyone know roughly how much in terms of cfm?

The part number I’m looking at is esr2102.

Also looked at donaldson g110120 but very high flow rates and as much as it’s right geometry i think it’s too large to fit under bonnet of my disco.

The round defender tdi one will help remove all the pipe bends from the snorkel (frictional losses) and hopefully have better flow if somebody here can confirm for me.
