This homemade kit allowed my N55 35i to utilize the double intake openings that the X5D is designed with.

I bought the OEM intake duct from the dealership for 35d (part #13718570289) and then sourced the hose and clamps to adapt to the intake box.

No idea if there’s any real power gains but the butt dyno liked it and I felt good knowing both intake ducts were open and feeding air.

All in I spent around $225. The intake duct alone is like $150+.

Located in Charlotte, NC.

Price includes shipping.

Did you reshape that one end from oval to round ?

I think that’s due to the pressure from the clamp overtime. I ran this for about 2 years
