Thanks mate :smiley:
After 80 miles the trims are going negative, so that insert is slightly too thick.
Joshy:
Has this intake system been tested by any of the members on here?
It is enclosed, so I'd assume it would be quieter than an open cone, but i could be wrong!
The second link is the "gen 2" version, although I do not know the differences between the two.

Enjoyed that read, including the ghetto sleeve insert. Not sure that is any better for smooth flow than an additional join further down the intake, but at least it is helping
How far negative are we talking?
As for the MAF insertion depth, mine is nowhere near centre, it is near the edge as the Revo one is and my trims are perfect. I found by changing the mounting depth and mounting it central in the pipe it significantly reduced the reading and gave me the 10-15% positive trims I had previously
Whats the next plan? A thinner insert?

Another crazy money intake! Looks good though and will be quieter than open cone for sure.
It's nice to see an intake with a flex coupling, too.
V2 appears to just have that bulge in the filter housing compared to V1, which is similar to the old Carbonio/APR intake. I'm sure they will try and baffle you with science as to why that shape is beneficial, but 90% of it will be marketing flannel :grin:

Yeah the step from the insert won't aid smooth air flow!
It's on -2% after 71 miles. I can already feel in the way it drives that number will grow. I don't like seeing negative trims. It's safer to add fuel than subtract it.
OK, I will ignore the mounting depth for now. Some things can't be explained / reasoned unfortunately!
I can't find any stainless tubing with <1mm wall thickness, so I think it's going to be a back to the drawing board approach.
I might get the 42DD clip in MAF housing to use with the stock TIP and work back from there. I'm thinking these aftermarket pipes are too long which reduces the off boost responsiveness, certainly in K04 applications. I've got a few ideas floating around my head, so I'll have to see what's available.
