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

I love these!
Size: 30, Color: Athens Mid Short - Medum Indigo
Wow! I got these for$20! They fit just like the 501 pants to me. . The only thing I'd change is s little less fraying on the front but other than that these are a broken in lived in look for $20!

Wish the sizing was more accurate, but still cute!
Size: 33, Color: Luxor Heat - Light Indigo
These shorts are super cute! I really love the color and style, but the sizing is WAY off. I typically wear anywhere from a 12-14 in jeans. After looking at reviews, I sized up to order what I thought would fit like a 16. Unfortunately they are pretty snug. I am hoping after a few wears they will loosen overtime. I would size up two sizes if you are a curvy girl like me! They do not have much stretch to them, but good quality denim.

Perfect shorts!
Size: 30, Color: Athens Mid Short - Medum Indigo, Size: 30, Color: Athens Mid Short - Medum Indigo
I was worried these shorts wouldn’t cover enough of the butt area or that I wasn’t thin enough to wear them especially since most of the reviews are from thinner people. but OMG, they’re perfect. I’m 5 4, 152 Lbs and size 30 is absolutely perfect. Size 29 would be small for me.

Cute distressed shorts but size up!
Size: 30, Color: Athens Mid Short - Medum Indigo, Size: 30, Color: Athens Mid Short - Medum Indigo
Love these shorts! These Levi’s run small. I usually wear a 28 and ordered a 30 because that’s what was available. I’m 5’1”, 135 lbs for reference. They’re distressed and shorter in front which are perfect for us short gals.

My go-to shorts this summer
Size: 30, Color: Athens Mid Short - Medum Indigo
These are easily my favorite shorts this summer. The fit is super flattering and they have that classic Levi’s look that never goes out of style. The denim feels high quality and holds its shape without stretching out too much during the day. They’re comfortable once you break them in, and they pair well with pretty much anything. I also like that they’re not too short or too long—just the right length for everyday wear. Definitely worth it if you’re looking for a staple pair of denim shorts!
