E82 N52 intake upgrade questions



Has anyone done the 330 3-stage intake mod on the 128i or 328i N52 in Ontario? If so, where did you get the parts and who did the work?

Where did you get the ECU flashed or what mod did you apply?

Did you also upgrade the air filter assembly?

When finished... how do you like it?

Thanks

If your signature is accurate and you have an X3 3.0si, it is essentially N52 with the 3-stage intake. So, that's what your 128i would feel like in terms of engine response, power after the upgrade.

Air filter box upgrade is not necessary.

I did this on my 328i. Got the parts off the forums, did the install myself and got the tuning done to activate the DISAs and improve the power even more. It totally transformed how the car feels to drive, especially the unexpected boost in low end torque. So worth it, I only wish I did it sooner.

I think you're right that X3 does have that setup, I like the performance of it in general but the increased size and weight hides the advantages vs the 128i. The 128i feels far more nimble.

I have no complaints about the stock N52, just happy to add a bit more under the hood if it's relatively straightforward.

That said, never occurred to me that a wrecked X3 LCI might be a good donor car for this, I was thinking only about 330i cars.

Now if I could just figure out a reasonably priced way to get an LDS into this thing... cost me $280 and about 2 hours to accomplish an LSD swap for my E36. Looks like I'd be lucky to get away with $2800 with the E82.

Where did you get the tuning done and what was the cost if I may ask?
