Intake walnut shell media blast....
Dealer quoted me "around $700.00" to have this done to my 2013 335i Msport......
What say ye bimmerpost? Is that a rip off? And before you say "you could do it much cheaper if you did it yourself". I know I could, but I don't have the time nor facilities available to me to do this. Although if I still had my old garage, I likely would attempt it because it doesn't seem that overly complicated. |

Are you looking for dealer only? Surely an indy could do it for cheaper. Even here in Canada, they range between $300-400. Downside of an indy would be you need to arrange your own transportation.

Yeah I would just go to an Indy if I were in my home city. Problem is here in Little Rock, I haven't been able to locate any euro oriented shops that might perform this service. Plus, with my job, I have to have transportation at all times.
If I was still in Charlotte I would just go to Eurowise. |

Bavarian Autosport sells kits for the N55 that hook up to your shop-vac and shop air in packages between $250-$600.
I feel like I'll buy myself their kit when I need to clean my intake valves (I have a PI so my valves are pretty clean) and so then I'll have a walnut blaster and several cleans for the price of one professional one.

The best way to determine how often you need to clean your runners and valves is just by actually looking at the state of your valves with your manifold off.

I have same car as you. Purchased everything and did it myself.
The N55 does not need walnut blasting, at least not at 50K. Whatever BMW changed from n54 to n55 made a huge difference. |

Of course this isnt exact science because it depends on a lot of variables, but if one to drive like you, what would be your recommended time/mileage/period of "blastin nuts" on N55s?! Do you have any phots of yours (before/after)? Quote:
How would one acquire a PI and what are the benefits and drawback of the PI? How does your "Pubic Incinerator" go about to clean your "valves"? Does it hurt? |

A port injection kit is beneficial as an additional source of fueling to power higher power applications such as engines tuned to run E85 fuel. E85 has higher octane than pump 93 gasoline, which allows the engine to produce more power but since ethanol has a lower specific energy than pure gasoline more fuel is needed to produce the same or increased power levels so an additional source of fuel is required. This is where a port injection kit can become beneficial as the stock high pressure fuel injectors and fuel pump cannot supply enough fuel to the combustion chamber to enjoy the higher power benefits of running E85 fuel. But, as with all things, the more complexity you add to a system the more components exist that can fail and there are more things that can go awry.

DIY -- a worthwhile project
I did this on an 07 335i by purchasing a compressor from HFreight and the BMW wand and vacuum intake adapter from ECS. Yea the hopper and shells were from HFreight as well. Once you do the job 1 time -- you can cut the time in half the second time. So that was on an N54 so now that I have an N55 in the F22 my cost will have been spread over 3 cleanings. I did purchase new intake seals but overall not a big cost. Plus it is a good bonding event with your car.

More info on this as I just crossed 50k and was thinking about buying my own kit and getting the valves walnut blasted. Should I not bother?

While doing my oil cooler/filter gaskets, I peeked into the intake valves on my car with ~70k and they were in pretty good shape.
