High-flow drop-in upgrade for BMW 1 Series M135i F20 F21 from 06/2012

Unlock sharper response and stronger breathing on your M135i with this Pipercross performance panel. It swaps straight into the factory airbox, delivers outstanding flow, and is built to last. We run this on our own cars and customer feedback has been superb, with crisper throttle pick-up and a sportier induction note without unwanted cabin drone.

Why choose this performance panel for your M135i

• Direct OE replacement for the standard element - no modifications required
• Up to 30 percent more airflow than the factory paper element for improved engine efficiency
• Three-stage foam construction captures debris effectively while maintaining strong flow
• Longer service intervals compared to cotton gauze options
• Easy maintenance - the open-pore foam resists clogging seen with V-groove styles
• Flow-bench proven to support gains in power, torque and fuel efficiency
• Backed by a lifetime guarantee for road use
• Proudly crafted in Northamptonshire, UK

Engineered for performance and protection

The triple-density foam element uses progressively finer layers to trap larger particles on the outer surface while protecting the engine from fine dust on the inner layer. This design maintains airflow as miles build up, helping your N55 breathe freely on both stock and tuned setups. Ideal for drivers seeking a simple intake upgrade that supports Stage 1 or Stage 2 style tuning while retaining the original airbox and cold-air feed.
