Due to weak plastic construction, the factory plastic crankcase ventilation breather hose is known to fail. After years of exposure to piping-hot engine bay temperatures and chemical-laden oil vapors, the corrugated plastic tubing can crack, crumble, or fail altogether.

We set out to bulletproof your N20 PCV system with a durable silicone breather hose, designed to provide a comprehensive upgrade and permanent replacement for the factory plastic hose. By replacing the flimsy, heat-hardened OEM plastic hose with a four-ply fluorosilicone hose, you'll experience peace of mind knowing your N20 is free from the inevitable return of oil leaks, vacuum leaks, and drivability concerns that would have been.

This breather hose is found at the front of the engine, and is used to connect the inlet pipe to the valve cover. It replaces OEM part number 11127588417.

Features:

Silicone construction ensures a durable replacement that is sure to outlast OE plastic
Designed as a direct replacement for the factory breather hose
Retains heating function and OE electrical connector
Design:

Four-ply wire-reinforced fluorosilicone hose is designed to resist degradation due to exposure to oil vapors
O-rings are pre-installed in OE connectors for a lasting seal
Includes pre-installed zinc-coated hose clamps for durability and corrosion resistance
Product Development:

Our Silicone PCV Hose Upgrade was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modelling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

The ultimate intake for the E46 M3, made from prepeg carbon fiber in the same weave as the Genuine airbox for a OE look. The Karbonius airbox also features carbon fiber intake trumpets in place of the factory's plastic trumps, and are finished to a ultra smooth finish for perfect airflow.

At Turner, all our Carbon Fiber Intake Systems are top-of-the-line custom-engineered products that we develop in house. Our Turner S65 Carbon Intake is a monster that perfectly compliments the high revving 4.0l V8 engine. Add in a full carbon plenum and you have a recipe for greatness! The intake benefits start right at the motor; the plenum offers a larger interior volume and full carbon design which helps boast the intoxicating roar. Directly connected to the plenum is a full carbon intake tube with a substantially larger cross sectional area with smooth transitions which results in more airflow available to the engine in high demand scenarios. The inlet tube mounts securely to the full carbon heat shield and is mounted in factory airbox locations while retaining the factory cold air induction tract from the hood. Housed inside the heat shield is a behemoth cone filter to ensure proper filtration and maximize airflow. Turner's S65 intake and plenum is designed with air flow and induction in mind. The intake flows like no other; during testing, the Turner intake outperformed the flow-bench at over 750CFM, a massive improvement over the factory intake.

Here are the benefits:

Full carbon plenum and intake for a full engine bay transformation
You get a beautiful carbon heatshield, one of the only full carbon fiber heatshields available.
All the flow - the air on demand will make sure your engine always has room to breathe.
Increased throttle response.
Added induction noise for an intoxicating driving experience.
PART DESIGN:

Designed and engineered in-house using state of the art 3D laser scanning and CAD technology for precision fitment
Full Carbon Plenum construction with internal bracing and velocity stacks
Hood Inlet Scoop - Directs the flow of cool, ambient air to the heat shield, and directly into the air filter. Seals off with the factory rubber gasket on the lower side of the hood inlet.
Full Carbon Fiber Heat Shield Assembly that utilizes OEM air box mounts and integrates with the factory air intake tract from the hood.
Monstrous 9" cone air filter to maximizes filtration that is able to be serviced/cleaned.
7"x5" Carbon Fiber Inlet Tube providing smooth, direct airflow from the behemoth air filter directly into the plenum.
Fully compatible with the OEM Secondary Air Injection emissions system. Factory hose lock and location.
Full carbon fiber plenum with bracing and carbon velocity stacks.
