I've been out of the loop on all the progress that's been going on with the 12v group for about a month now. Also, I'm not nearly 1/50th of a percent as knowledgeable as you folks. So if someone would be kind enough to list what new things have been created over the past month or so (and i'm not against having someone list EVERYTHING that was ever made for the 12v motor ;) ) that are for sale, please do so here. Your feedback and contribution is much appreciated. TIA!!!

Velocity Stack, Bored out S3 MAF, S3/S2 Throttle Body, 3" Silicone Induction kit for the MAF to TB and a few other tweaks he offers as COTS products.

The one with the upgraded fasteners.

A few horses less lost are a few horses gained. ;-)

I think UrS4 somehow modified the fastener tabs and included better screws with the EFK kit. I'm not sure about the nationality of those parts. :D

btw, i'm assuming if i went with any of these new goodies, i'd have to go back to using my stock airbox?

;0) I'm having withdrawals from the A4 forum. *ducks head*

integrated velocity stack. If it does you could benefit from removing the MAF screen.

There's also this airbox inlet velocity stack but not for the A4 (90 only):

are there any problems with having a longer maf to plenum tube than stock? i'm assuming that since i have a cone intake, i can just run an extended tube from the maf stock location down to the bumper and relocate the filter down there with no problems to the f/a mixture?

If your cone filter has an integrated velocity stack and you want to remove your MAF screen you don't want to move your cone too far away from the MAF. This means you'd have to relocate your MAF and reroute the MAF's wires also. You probably don't want to move your MAF down too far because then you run the risk of getting it wet, etc. The best thing too do is something like JustDave's setup:
