OVERVIEW

The Evolution Racewerks B46/B48 Charge Pipe Kit replaces the factory plastic charge piping on 2016 and later BMW four cylinder models. The factory pipe was never designed for the boost levels a tune produces and splitting is a common failure; this kit replaces it with mandrel bent 6061 aluminum backed by a Limited Lifetime Warranty.

Charged intake airflow has a direct effect on throttle response, turbo lag and maximum power, and smooth bends with minimal obstructions are what matter. The upper pipe uses a long smooth transition from 2.5" at the turbocharger outlet to 3" at the throttle body, matching the factory approach. Competing pipes run 2.5" all the way to the throttle body, which leaves a step right at the throttle plate. Evolution Racewerks states the result is better throttle response and less turbocharger lag.

Every flange on the kit is CNC machined for precise fitment and the whole assembly is TIG welded. The kit consists of an upper and a lower charge pipe, and both are included and required for installation.

SPECS

Two-piece kit: upper and lower charge pipes, both required for installation
Lightweight high grade 6061 aluminum, mandrel bent piping
Long smooth transition from 2.5" at the turbocharger outlet to 3" at the throttle body, where competitors use 2.5" throughout
Retains the factory style o-ring c-clip lock flange
Precision CNC machined flanges for leak free connections at both the turbocharger and the throttle body
Precision CNC machined MAP sensor and IAT sensor flanges
Beaded ends with T-bolt clamps so the intercooler piping cannot blow off under boost
Two 1/8" NPT threaded bungs for methanol or nitrous injectors
Compatible with the factory electronic diverter valve
Finishes: brush (plain) or mirror polish standard, and optional Type III hard black anodizing for a stealth OEM look; hard anodizing also hardens the aluminum against damage
TIG welded construction
Made in the USA
Warranty: Evolution Racewerks Limited Lifetime Warranty.

PARTS INCLUDED

Upper charge pipe
Lower charge pipe
T-bolt clamps
All hardware required for complete installation
