Injen SP Series Short Ram Intake Kit for BMW N55 135i & 335i (E82 E88 E90 E91 E92 E93, 20112013) Wrinkle Black SP1126WB

Injen SP Induction System - Wrinkle Black - SP1126WB

Give your N55-powered BMW the airflow it deserves. The Injen SP Induction System in wrinkle black transforms response and soundtrack on the 135i and 335i, replacing the restrictive factory airbox with a free-flow, open-cone setup that lets the turbo breathe. Expect sharper throttle, quicker spool and a punchier mid-range, with dyno-proven gains of up to +15 hp and +18 lb ft on the N55 - all without an ECU remap thanks to Injen MR Technology.

We have run this kit on our own N55 and fitted it for countless customers. Feedback is consistently positive - clean fitment, quality hardware and a purposeful induction note that makes every drive more engaging. If you want a simple bolt-on upgrade that delivers real-world performance and noise, this is it.
