Wehrli Custom Fabrication WCF100418-CRO Stage 3 High Flow Intake Bundle Kit Candy Red Orange

The Wehrli Custom Fabrication WCF100418-CRO Stage 3 High Flow Intake Bundle Kit is a comprehensive bolt-on performance upgrade finished in a striking Candy Red Orange powder coat. This Stage 3 kit combines Wehrli's high-flow intake assembly and intercooler piping with a 3.5 in. downpipe into a single package, delivering increased airflow to the turbo and engine for improved efficiency, throttle response, and faster turbo spool-up. No tuning is required — this kit retains all factory connection points and sensors and installs without additional modifications.

On the intake side, the kit replaces restrictive OEM plastic components with a 4 in. aluminum intake pipe featuring smooth, aerodynamic mandrel bends for optimized airflow. A 3.5 in. intake horn with PCV port and surge ring improves intake air velocity and volume while also delivering a more aggressive engine and turbo sound under acceleration. The enclosed aluminum airbox with lid houses a dry air filter assembly with an Outerwears hydrophobic pre-filter cover to protect the MAF sensor and turbo from contaminants.

The intercooler piping portion of the kit upgrades both sides of the charge air circuit. The 3 in. driver-side (hot side) intercooler pipe is manufactured from heavy-duty 14-gauge aluminum and eliminates the OEM middle boot joint for improved flow and durability. The 3.5 in. passenger-side (cold side) intercooler pipe features a CNC machined flange with a black anodized billet aluminum adapter and double O-ring seal to eliminate boost leaks. The OEM clip ring design at the Y-bridge connection is replaced by a high-quality silicone boot and stainless steel T-bolt clamps, enabling the system to hold higher boost pressures without leaking.
