Cold Air intake question
Has anybody used the AFE Cold Air Intake Momentum Pro 5R fits BMW 12-16 M5 (F10)/M6 (F12/13)? Any feedback on power and ease of installation appreciated. Any issues?
Thank you |

Not worth it when people dyno up to 800whp on the stock air boxes. If you don't want to run a front mounted CAI like RK carbon then remove the carbon filters, get a pair of BMC filters for the stock air boxes and close up the holes on the bottom of the air boxes. You'll be sucking in air only from outside and it won't change the noise level much. Between that option and the AFE there is no performance difference that you are going to hear or feel.

IMO, the CAI are inferior designs to the air boxes like Dinan or even stock. The factory system was designed to shorten the distance of the air flow to the turbos, a CAI increases the distance and blocks about 40% of the radiator cooling surface:
Lastly, the intake will add virtually no power by itself. You'll want to pair with a tune, and the tune itself will be what bumps the power up, not the intake. Summary: stick to stock (remove charcoal filters or add an aftermarket drop in) or buy the Dinan box which is essentially a glorified air scoop with elements of the CAI through the snorkel.

I agree except for Dinan, I have never seen an M5/6 dyno over 700whp on the Dinan intake. Also the benefit of the cold air front mount intake is that you are only sucking in cooler air from outside of the engine bay and you get an amazing sound. The stock intake can be sealed to only suck in air from outside, and with scoops attached, and performance filters you can push over 700whp with supporting mods so it comes down to preference because you can do the same with the cold air intake and there have been no issues like raised engine temps so you go with what works for you.

So,for the dimwits like me who are hesitant to start mucking about under the hood, is there some sort of DIY guide for what to do and how to modify the stock system?

https://f10.m5post.com/forums/showthread.php?t=801214 You have to open up your air boxes and that is very straight forward, if you can't do that just bring it to a local shop that knows BMW's and they can do it for you for cheap. Once you take out the filters you'll know if you have block off plates or if they are open at the bottom. then you can either seal them up, I used a piece of sheet metal and some dynamat so I can always remove it. Buy the performance filters first so when you open up the boxes at least you can remove the charcoal filters and the OEM air filters and replace them. You can also get a pair of hood scoops to help feed cold air to the boxes. RPI makes them. |

I just removed the charcoal filters and have the M performance Titanium akrapovic exhaust on my M6, what should I expect in terms of performance and exhaust sound? How much more restrictive are the OEM filters than the BMC performance filters?
By the way, when I removed the yellow filter underneath was a "snorkel" and not an opening that I could cover, just FYI. Thanks again for the pointers |

I did some search at the M5 forum and it appears that there are MAF issues with the filter oils and there is no confirmed improvements over the OEM filter (feedback on the OEM filter is positive) anybody has had MAF issues after installing the BMC air filter? Just doing some homework before installing.
Thanks |

My intake air is around 50 odd degree Celsius in my climate, drawing from the engine bay, primarily. If I were to go for a stage 2 tune, I have been advised I’ll need reduce the charge temp, and the intakes being moved would be the best way to get cooler air going in. And to those saying not to bother with an intake, wtf? An intake and exhaust will get your car breathing much easier for when you do get a tune. I’m getting a Stage 1 done shortly, and that should give me. 680hp, or over 500kw if that’s your thing, and 850nm of torque. |
