The OEM BMW diverter valve and charge pipe are prone to leaking under normal boost pressures, this results in reduced power and less performance. Our ETS Charge Pipe replaces this flimsy factory part with a full 3.0 inch pipe made from 304 stainless steel, which is designed to handle stock boost levels and beyond without leaking.
Unlike our competitors, we designed our 135i and 335i charge pipe to incorporate the factory 45 degree elbow. When matched with our intercooler kit, the complete cold side piping is replaced with 304 stainless steel, 4-ply silicone, and Breeze T-bolt clamps. Doing this allows our charge pipe to work with LCI equipped vehicles without issue.

Bought with a HKS bov flange. Bov is super snug and doesn’t leak at the seal. Uses rubber sleeves as opposed to the C clips the original pipe had not sure if I like that better but it seems to work just fine. Should also note the flange is far back on the pipe I was worried it would interfere with my CAI but it works.
Great product ,super easy to install
The best quality charge pipe on the market. Definitely recommend purchasing this!! Every fit perfect no issues
