Replace BMW OEM Part 13718601684

The Forge free-flowing charge pipe kit will increase flow and improve the reliability of your B58 engine from BMW. These high-quality aluminum pipes are a direct replacement and will fit in place of the OEM plastic pipe.

The OEM pipe can become brittle and fail under increased boost pressure, so we have developed a replacement with an increased diameter, which helps to reduce turbulence and maximize flow into the engine.

  • Larger diameter giving increased flow compared to OEM
  • CNC machined billet couplers
  • Mandrel-bent single piece aluminum pipework
  • Minimal airflow disruption
  • Integrated water/methanol port and blanking plug supplied
  • All fitting hardware supplied
  • The alloy hard pipes are powder coated to allow for a more durable hard wearing product
  • The Forge silicone hose in this kit has been designed to include a high-quality inner liner of modified silicone known as Fluorosilicone. This means the hoses are suitable for use with either modern long-life coolants, Organic Acid Technology coolants (O.A.T.) or air containing oil mist. The construction of the hoses has been engineered to exceed that of the OEM fitments and will enhance any engine bay both technically and aesthetically. The use of a Fluorosilicone liner ensures that Forge silicone hoses are the clear market leader

Buy it
If you're looking for a comfortable thick and nice turtle neck this is the one. It's nice and form fitting nice weight to it to keep you warm. But not to thick that you cant just wear it on a regular sunny day if you wanted. The design pattern Is also very nice. Can dress it up or down. I bought the black and then immediately bought the rust orange color for my friend once he tried on mine he wanted one immediately so I gifted him one. He loves it. Definitely worth the buy. Excellent quality. I bought a Large 5"11 165lbs

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
