Initially thought of pop riveting a steel strap/flat bar across the existing holes with a drilled center to locate and centralize the hole saw but the timber jig & fixture worked very well and provided for a positive feel.

Some preliminary pics of my trial fit out of new 4" snorkel / 9" pod airbox and the 3"ducting to turbo inlet. Had to modify the radiator shroud to fit box and to lift it so that the box can drain water to its inlet end. All fits well with the JT cooler. Will write up in more detail later on.

First time journey, poking along but satisfied with progress and need to juggle activity with paddock duties.
The 4" thru airbox is made by small time self employed boiler maker. Does good work. Builds these for TD42 and ZDs, mine (CRD) has the TD jobbie x 330mm long, fitted up well with mod to radiator shroud and has good end clearance between inlet end face to base of pod filter. Uses a 9" K&N (KNRE-0870) pod filter. Supplies box only(filter not included) for $340.

Very neat mate, I cut a square in mine, painted cuts, no pinch weld, job done...lol
Came across an old thread of yours doing the square hole, could be wrong here, think you used an angle grinder. Recon I would have lost it and come straight out thru the outer guard..lol
Was easy with the wooden jig/followers I made to guide the 5" hole saw. Used the body saw to cut the elongated hole in guard and was so fast. Only needed a touch up with a file. Will get around to posting up.
With the procharge stage3 h/f turbo, this 4" snorkel and pod airbox has made such a difference, improved spool and really notice ability for torque to hold low down, especially 4&5th as was a bit laggy prior. Hear the induction air full on rushing thru Jonny Tig cooler and seems much easier on turbo as cruise boost runs lower especially at lower eng loads. Even improved the all round fuel usage. Doing tune on rollers next week maybe running a bit richer.
Pleased, just keep the window up with wife in pass seat, tomorrow will be her first run should be interesting.
Now the 4" induction upgrade complete, went to ECPT (Tuggerah, NSW) last week, put it on rollers and had tune 08 CRD.
Have been progressively doing build up(last 15months). Stock eng except:
NADS
Remap
Procharge stage 3 h/f turbo
Tillix/needle (Max B 26psi)/13.5"Hg VNT actuator
Jonny Tig cooler
Ben Lipscombe - 9" K&N Pod / 4" thru airbox (3" to turbo)
4" fwd facing snorkel w/safari air ram
3" exhaust turbo back w/ muffler and cat
Had a couple of tunes along the way, latest being after install of JT cooler and 4" induction.
Running 33" m/t
Leaned it off from AFR19:1 back to 20:1, could have put more fuel but this has provided a good reliable result: 136rwkw and 512 N-m/4th gear.
Dyno results attached, my CRD "Blue Trace" / the "Red Trace" is for comparison purposes of a stock 2010 CRD on 33s and 3" exhaust on the same dyno.
Achieving 20psi Boost @ 1900-2000 rpm, max B 26psi @ 2200rpm (good to drive).
With the upgrade to JT cooler and 4" induction gave me an extra 70 N-m. From 378 to 450N-m and with the tune last week now producing 512 N-m. The trip back home from Tuggerah, NSW via Sydney (400km). fuel usage 12.5l/100km.
