Evolution Racewerks Charge Pipe Kit – BMW B46 / B48

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
