The clip that holds the charge pipe in place, under the left side of the engine is the most difficult. The two electrical connections are a little fussy to get off. Beyond that, just 3 screws that are pretty easy. Depending on what you are replacing it with, you may have to reuse the gasket, which can be tricky to remove without damaging it. Some charge pipes come with a new gasket. I think there are videos on YouTube that show you the process.

My BMW tuner tells me the plastic charge pipe used on the B48 and B58 are the weakest link on the engine. They can blow out. I was thinking of replacing mine, but I wanted to make sure it would not hurt my warranty.

I would be very interested in learning which CP folks are using.

My choice is Kies Motorsports. I don't know if they sell the B48 model, but it is shown here: https://www.kiesmotorsports.com/prod...48-charge-pipe

Thanks for your advice I will have a look on YouTube, I’m out of warranty at the end of February so can start to put a few mods on 👍

My son-in-law did the charge pipe on a friends 2018 330i (I think that was the model). I watched. I think it took longer to figure out what needed to be removed and how, than to actually do it. We used my M40i as reference, too. There weren't any YouTube videos we could find at the time. The B48 and B58 are very similar.

I am thinking of a charge pipe, down pipe, Pure 800 turbo and mild tune that adds 4.5 lbs of boost for 93 octane.... when the warranty is up. Everything is a direct replacement for OEM and requires no mods or cracking the ECU.

I’m thinking of getting this one, about £250 is seems easy enough to fit.

Looks good to me. About the same price and same material as the ones I'm looking at.

[Timdon]

Are you in the UK ? Which ones are you looking at?

[Balr14]

I am in the USA. This is the one I am most interested in:

I fitted my new charge pipe decided to go for the MTC £200 great quality and an easy fit , the hardest bit was getting the pipe over the turbo and fitting the retaining clip.
