aFe Pro Cold Air Intake System (N54)

Filter type *

This is the Stage 2 AFE intake system for your 135i/335i/1M/Z4 with N54 engine.

In our opinion, this is one of the best cold air intakes available for the N54 engine. The dual cone design offers much greater surface area than the stock restrictive airbox thereby allowing more air to enter leading to greater pwoer. In fact it out flows the original N54 BMW airbox by 98% and we have seen up to 10kw at the wheels gained on our dyno. In addition it helps the engine breathe up the top end which is where the restriction in the original airbox really starts to show, thus stopping power from dropping off so sharply.

The supplied heatshield also helps alleviate some heatsoak issues other dual cone intakes without a heatshield may suffer.

Unfortunately 'open' air filters are not legal in all Australian states and territories so you're advised to check with your governing roads and traffic authority.

This item will generally ship in 7 days however may be sooner if we have stock available.
