ETK says no charcoal liner on EU models. If you can follow up to verify, that would be great!

Finally got round to doing this and can confirm there are no charcoal filters on my UK spec. car.

One point, the DIY guide suggests just 7NM/16NM for the Strut brace bolts. This seems a little low as that's barely hand tight.

Great T.O. !

Definitely second the advice of a long T-handle for the T25. Also are the 10 mm screw is shorter than the others so be aware of that you can easily be dropped.

21 minutes, hood open to hood closed.

Tried to delete charcoal filters on EU-spec model. They aren't there. Seems like they are deleted from factory. Bought car brand new.

Bolts are 6mm and 8mm shank, they don't need to be torqued much.

Thanks for the feedback on the EU side, appears the charcoal liners are a US thing only.

I'm in CA and for emissions purposes and to keep the car as stock as possible, I'd like to keep the charcoal filters but would love to hear the turbos a bit more. Can anyone comment if there is an audible difference by installing the BMC and keeping the charcoal? Thanks.

Great write up , install was super easy and I actually thought it was kind of fun removing the strut brace and feeling how light it is! I can hear a slight increase in spool sound in the higher gears as others have said. Not sure if the new filters or removing the charcoal though. Excited to hear how it sounds with the JB4 when it comes in.

I didn't have any charcoal filters, but I did hear a marked difference when I installed the BMC ones. It was amplified much further with the addition of JB4.

Thanks for these excellent instructions. Just removed my charcoal filters and put in BMC filters. Strangely enough the only difficult step was step 1. The head popped off one of the compression rivet pins - was a pain in the ass to get out! The rest was smooth sailing.

I skipped steps 5 and 13.

These BMC filters guarantee containment of all impurities from as small as 7 microns, as compared to the OEM's 10 microns.



BMC air filters are produced using a full molding system that enables the characteristic red filter to be realized from a single mold with no welded joints, thus avoiding easy breakage. The rubber used in BMC air filtering systems has a long life, is very durable and has optimum adhesion characteristics to all shapes of airboxes. BMC filters are made of a multi-layered cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity. All BMC air filters are pre-oiled, and they can be washed and regenerated by using an appropriate regeneration kit.

Installation

When re-installing the carbon brace can you hand tighten? Is the torque wrench truly necessary? Also did the lb/ft you reference OEM spec?

Thanks!

Hand tighten to snug will be fine, most shops (including ours) will verify with torque wrench.

Basic torque wrench is about ~$75 at your local Sears/Craftsman, always a good investment.

A lift isn't required for filter swap. Very simple DIY.

Someone was telling me that I should not remove or reinstall the strut bar when car is on the floor... I told him he is wrong and he argued that "it should be on a lift with wheels off the ground" ... This is why
