I meant to ask what's the easiest path to getting the filter in and out of the car?
Least things to remove, that sort of thing. The eventuri was already installed in the car so I'm not familiar with it.
For your situation where you didn't install it in the first place, go to their website
https://www.eventuri.net/products/lotus-emira-v6/ and download the installation guide.
Here's what it looks like out of the car fully assembled and the way it will be oriented when in the car.
To remove the unit, there are 2 bolts on the top bracket to remove. The nuts behind them are welded to the bracket, so you only have to remove the bolts but HANG ONTO them as you remove them so they don't fall down into the abyss below.
Squeeze the top of the MAF plug and the plug will pop out. It removes easily so there's no need to pry.
Loosen the band clamps on each end of the connecting tube, but you won't need to pull the breather hose shown by the green arrow. You can just swivel the tube up and out of the way with the breather hose connected. When pulling the ends of the connecting tube from the supercharger inlet and the Eventuri, HANG ONTO the band clamps so they don't fall down.
Depending on how the unit was installed originally, there should be all or some of the clips circled in red on the picture below that need to be slid up and off the tabs they're on.
Next push the 3 rubber hoses down and out of the loom on the bottom of the Eventuri, and lift the battery cable up and over the end to clear the loom. You don't need to unbolt the loom.
Now you can carefully rotate and lift the Eventuri up and out of the engine bay. Reinstallation is the opposite of the above. I've put the full disassembly and filter cleaning procedure in my project thread Adding Lightness.
