Exactly, that is the only difference in the 4xx the cooling

@nordschleife666 exactly, Eltech ones

The one in checked had a thin opening like drawn in the picture and only to let the air flow (minimal) towards the rear If there were any air flow to the front one I guess they would have also added a drainage hole In the end I went down the 380 cup version for mine, fully open

I inspected a 430 FE today, even below the wheel arch area The front and bigger part of the vent is closed, no discussion ...no air will go through that one ..ever The rear one, apart from the drainage hole has a super small opening that will allow air flowing through the smaller aperture I seriously doubt how functional could be as the aperture is very thin

And I guess that Lotus didn't think about adding a mess 🤣. It would be a 100% lotus move

Can you post a picture of the opening in the wheel arch liner ? Not sure how something is open when it looks fully closed. In all the cars with vents you see clearly when the air goes through ( on the GT3 RS for example) Then misteriousky there's pictures of 430 cup where you can see them open.

Just in case anyone has the same doubt, this is completely normal. Verified in other cars (410 and 420 FE)

There's no special part for the 430. The reference is exactly the same. If you inspect them and you inspect the wheel arch from below they are closed https://parts.bellandcolvill.co.uk/?i=1341063&MAK=1&MDL=42&TBL=11554&SMA=0&SMO=0&ST=b138u4077f&SC=0&PBID=681770

If you check the parts on deroure, it should be wide open in both 380 and 430 cup. That clam vent without the wheel arch hole is useless and 100% cosmetic ... Another Lotus screw to the list ...

At the 3yr mark when I replaced mine with a moroso one they were ok Plastic gates that need replacement ...another genius idea from Lotus ....

I remember that in my Exige 410, until a point after a service last year, I could hear the fuel pump preloading when moving the key to the ignition position (after turning off the immobilizer). Now, in order to hear the fuel pump preloading I have to do: ignition position, back to pre-ignition and then ignition position again Is this something a lotus software update changed? Even without the fuel pump preloading, the car starts up perfectly I'm asking specifically for 4XX Exiges due to the fuel pump being different to the 3XX Exiges Regards

With new headers, y pipe, decat and no repro you are highly likely losing power

Front OEM are 6.8 kg not 7.5kg And the problem with 9.5 width on the rear is that you can't fit 295/30, for example A052 or AR1, which are miles away from anything you will find in 285/30 size

I think the wire connector you are referring to is for the exhaust valve switch

Very useful information, I will send you a DP next year as I'm planning to make the same move to US (but to Texas instead of the East Coast) Regards
