But again for like the 3rd time, I'm simply saying the performance gain is quite minimal and the $1200 is thus mostly for the CF dressing vs performance change. And the RK is even worse in that respect although much better looking IMO. This whole discussion should just be your budget. If you can afford to drop over $2k for the RK then do it. It's closer to a "cold air intake" as you're gonna get. If you can't and must have an intake for the "sound" then dinan is your only other option for $1200 for 2 filters and a new top to the oem air box that's simply taller to fit the larger filters and made of CF. I'm out cuz this is getting too lost in translation. GL OP! Sorry to confuse everyone.

Is it possible to use the Dinan filters with the stock box? The CF cover seems like a waste of $1,000.00 - the filters by themselves are $250.00.

The more I read about this the more it sounds like the BMW design is 'good enough'. It doesn't look like any sizable impact with the Dinan product at all. And, even the current filters being swapped doesnt look like much impact either - looks like BMC makes a version (K&N doesnt).
Even with an exhaust and stage 1 tune, the stock item might do the trick - just want to be sure Im not missing something. |

Go with the BMC's. I run them on my E70 X5M. Perfect for the price point.

Thats exactly what had me scratching my head too...the surface area on the K&N and BMC is smaller than OEM. And, they dont provide any CFM information for either like they do with some of their other filter applications - my take is that there isnt a gain by moving to these filters from the F85 stock system.

Hey guys! New to the BMW world, here. Just purchased my first (2017 F85) and am already in love! Checking out air intakes and didn’t notice any comments re the aFe. Any thoughts?
Also looking at swapping out the exhaust, but going to have that done by a shop that can tune it properly post install. Any recommendations? Considering the Eisenmann race and the Fi. Lots of folks seem the enjoy the Akropovic, but $7k is a little steep. If it’s worth it then I’d consider. What do y’all think? Thanks in advance! |

With the exhaust, start with the downpipes. If you live in NY you will pass inspection with catless DPs and a tune, not sure how that works in NC. This sounds better than any exhaust with catted DPs. You can run the stock mufflers with catless DPs and you will love it. Best bet is to scoop a set of stock DPs with shot cats and just drill them out, reduces waste-gate rattle bc the stocks are double walled.. went that way in the M5. |

Hey! Just installed the RK Autowerks air intakes, and boy do they look pretty. One question I have after installing - has anyone had issues with the filters coming off while driving? The O-rings are snug, but I almost had to force the filter portion of the intakes down into the area behind the grill. I have also used the included Velcro to reduce movement while driving; however, I’m concerned that riding around on bumpy roads could cause the filter to snag something and get pulled off. Does anyone have experience with this? Ever had the filter pop off while driving? (I’ve already searched other threads and came up empty handed).
On another note, Akrapovic exhaust should arrive tomorrow! Chose not to start with catless DPs because of the comments I’ve read re metallic sounding drone at low RPMs. Going to install the akra first and if I want something louder, I may go with high flow DPs. |

Once you have them adjusted properly and snug it should never fall period just make sure that your measurements are A1... you don't want the intakes rubbing the chassis.

I didn't realize there were measurements I needed to take. I did try to space them evenly, and at a point where they weren't putting pressure on the tubing between the turbo and the intake. Velcro'd to that little black piece there just before the intakes curve downward.

Hate to beat a dead horse here, but I sum this thread up as small if any performance gain, good looks, and great sound. Sounds like people that have the RK really like the added sound, does the Dinan intake sound just as good?

Only comment I will add is that you can't go stage 2 without intakes. Stage 1 adding intakes not much of a performance boost, if any.

Anyone looking at getting a Dinan intake x-ph.com currently has a promo code for 10% off (store-wide I assume) and free shipping. That'll save you ~120 bucks off the total intake price! I know it's not much compared to the exorbitant price tag for two filters and a CF intake cover but at least it's something. Just thought I'd share for anyone who might be holding out for a lower price. Or, you could also just wait for one to show up in the classifieds section and hope to snag it before one of the other vultures gets it.
