Injen SP1129WB SP Series Wrinkle Black Short Ram Intake, BMW 340i/440i/M140i/M240i 2016-2021

Description

The Injen SP1129WB SP Series short ram intake is a direct-fit performance upgrade for the BMW 340i and related models. Injen dyno testing shows gains of up to 14 horsepower and 13 lb-ft of torque. It replaces the restrictive factory intake with a less restrictive design that improves throttle response and works with the stock engine calibration.

At the heart of every SP Series intake is Injen's tuned-intake engineering. The 6061-T6 aluminum tube used on the BMW 340i and related models is designed to reduce restriction and turbulence, and Injen validates each design on the dyno so power increases arrive without compromising air/fuel ratios. This kit incorporates Injen's patented MegaRam (MR) Technology to help maintain safe air/fuel ratios while maximizing gains.

Filtration is handled by Injen's SuperNano-Web dry air filter, a synthetic, fully serviceable element that captures fine particles while providing a large surface area for airflow. No oiling is required, which keeps sensors on the BMW 340i and related models clean. When service is due, order Injen replacement filter part number X-1059-BB. An optional Injen Hydroshield pre-filter (1040BLK) is available for added protection from water and debris.

The textured wrinkle black powder-coat finish resists heat and blends into the engine bay. Expect a noticeably more aggressive intake sound when you get on the throttle. Installation is straightforward on the BMW 340i and related models, and every system is backed by the Injen Technology Limited Lifetime Warranty.
