Third party sealed snorkels for the IG and QM

[Ex-defender driver]

I am not sure as I had the snorkel and airbags done at the same time, both items had prices but no separate labor charge. I was only interested in the overall cost and did not even notice that until you asked.

Install time can be 6 to 8 hours for the OEM style Aluminum model.

Ask Rohan.

Will do. Ive texted him but not had an answer yet.

If you’ve done similar work and are somewhat handy, then you can definitely install yourself with simple hand tools and a torx driver set (like any other Grenadier work). It’s a bit of an exercise in patience, but simple mechanical assembly. Hardest part is pulling off the right front fender and accompanying plastic wheel shroud. Then don’t over tighten any of the plastic 3D printed FDM components. Plan for 8 hrs just to be relaxed.

Rohan will send you a google drive with access to instructions, videos and photos that are helpful.

Ahh brilliant - thank you thats very helpful.

Finally: Got the GrenX Aluminium snorkel on yesterday and buttoned it all up. Overall not a bad install took me about 6.5 hrs to do because I had to remove my right side rock rail (Agile) to get to one bolt on the fender.

One trick: use a light coat of WD-40 to lubricate the stainless steel pipe to 90* silicone coupler when assembling the fender back to the truck. Will help it all slide without binding up.

Would be helpful to have some extra hands. If you’re mechanically inclined and have fiddled around with cars and other things in past this isn’t a hard install. Just approach with an open mind and patience.

For the turn signal wire: use a hooked pick/probe tool and gently pull it through the fender and pass-thru, connect the light and then match the keying and twist (similar to replacing an old halogen bulb). Uninstall from the OE raised air intake tube works the same and there’s a locking tab that just needs to be lifted to release.

Overall: works as designed, I’m sure Rohan and Canna Fab have made small improvements since I ordered this kit back in June 2025.

Given the OE airbox does seem to leak dust a bit, the big win here is the upgraded airbox.

Installing the airbox is… fun… but not too hard. You’ll notice where to adjust the heatshield over the exhaust manifold/turbo (this takes very little hand force, and the car should be plenty cool by the time you get to this point). Then make sure the feet engage on the underside in the rubber grommets - note: they won’t fully engage. I’m likely going to add a velcro strap around the airbox and putt a couple of the M6 screws through it to secure over corrugations. And I put a bit of silicone coupler material, as a pad, where the box contacts the mount on the underside so it doesn’t mar and make noise.

Filter: I’m using the Donaldson PowerCore that I sized by measuring the flange diameter, box dimensions and CFM comparison to a Bronco 2.7 EcoBoost twin turbo. Same setup that I recommend to @KristinaM for their build. Seems to work well so far after 2 days of driving around town. Also have the pre-filter sock on it for a bit of water resistance. May never need to service that filter, beyond inspection.
Note: this isn’t a filter fully designed for this airbox and requires the two rubber rings that come with the GrenX kit to clamp onto inside the box.

Be mindful when you swap over the MAF sensor and look up how to disengage BMW wiring connectors on FCPEuro’s YouTube. (Try not to break the locks).

Sound: the aluminum definitely resonates a bit more than the plastic (as expected). Even with the Donaldson filter in the airbox there’s increase, but not annoying turbo whooshing around town at light loads. This is kind of fun and neat if you enjoy responsible engine sounds. Under full load you can hear a bit more induction sound as well. Louder with windows down than up, but audible both times and again not obnoxious or fatiguing. But apparent and fun. Not something to consider if you really want the snorkel upgrade and the cost doesn’t turn you away.

Solid quality bit of kit, that will certainly add a peace of mind and cleaner air to the engine.

Looking at the pictures of the individual parts, I'm wondering how the inner snorkel part is screwed to the outer one. Is there an opening through which you can access the screws?

Yes there is, it’s 6x M6 screws that attach the inner and outer plenums through the fender opening and then 3x screws to the fender and 2x to the top of the A-pillar with a new bracket that uses the top factory nutserts. The lower A-pillar mounting interface is not used and you should use the OE screws and some 1.5mm washers to take up the extra threaded length to seal those holes.

Super helpful post - thank you. I have one to do when it arrives.

I also had the snorkel outlet => crossover PU sealed ( Sikaflex FTW ) to ensure everything was watertight. Mirroring @LazarusTheGrenny I haven’t run into any issues with the Donaldson PowerCore G2 pod filter.
