As air flow is a function of demand (torque) I can't see how this would be the root cause, must be something else going on or a different reason why thset up is causing problems, i.e placement of MAF sensors, cross sectional area changed so the math does't add up in the DME tables etc.

I received the new intake lids today and after installing them and taking the car for test drive, the LTFTs were ~ -23 and ~ -12 for bank 2 and bank 1, respectively, at idle. With the filters installed they were -25 (sensor max) and ~ -20.

When the car cooled off, I put the stock mufflers back on with no change in the fuel trim but there is always a 10 -12 % difference between banks at all revs so I will take it in and have the dealer find out why there is such a large discrepancy between banks.

When I get the car back I will park it as is for the winter and probably swap the tail pipes but leave the stock intake in place, unless the dealer find something else.

That offset between banks is normal.

After a full inspection, the dealer didn't find anything wrong with the car so the CEL must've been associated to the mods. Maybe next year I will try again because they really do sound great.

Hi OP. Picked up a lease return M6. New to the forum and a little behind on the replies. BTW, great post! From reading many reviews and forums, I decided to try out this combo with a twist. I ordered the ramair on eBay with BMS intake to avoid the MAF failure. Nightmare on a previous M3 with oil collecting on the MAF. Maybe it was the users fault, but ramair seems to be a great alternative. I would like to add the scoop you posted if you are still open to sending. I can pay via paypal. Worst cast, it won't cost $2500 for trial and error. Thanks!

Glad it worked out! You can hear the spool up much clearer now. Even if no power is gained it is totally worthwhile.

No, I meant that it freed up the intake (as I did with RK intakes) and the spool sounds beautiful. SerbM5 just fit the unused ones I sold him (couldn't come to terms with cutting my OEM parts).

On another note, thanks for all your contributions!! Both via pm and on here.

Anyone tried this with 90mm & 175mm filter. Stock inlet pipework is 3.25" possibly making the 90mm filter neck more suitable than 80mm??
