Arrow The best Cold Air Intake System.

This sale has ENDED but feel free to send me a PM if you are interested, chances are that we will still honor the sale price for you. If not, we can work something out!

Like the thread title suggests, this CAI System is currently the BEST on the market for the below models. Featuring the highest HP/Torque gains for a CAI on the market, plain and simple.

So, what makes this system so special?

A true cold air intake system relocates the filter outside of the engine compartment to deliver the coldest air inlet temperatures possible. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. But that's only part of the power equation. Tuning the inlet pipe in length and diameter to match the engine's resonance helps move more air to the cylinders, this tuning allows you to deliver large power gains.

This CAI is very similar to the popular "Dinan Tube Style CAI". The Injen CAI went a couple steps further when compared to Dinan however. The Injen system not only includes a Heat-Shield, but also features a full replacement of the OEM upper intake boot providing less flex and more consistent air flow. You also have a choice of two different finishes, polished aluminum or gloss black.

1998-2000 BMW 328 (E46)
2001-2006 BMW 325 (E46) does not fit 325 models that are equipped with the M56 engine.
Sadly Injen hasn't manufactured this intake for the 330 models yet, in the near future we will be putting together a list of potential buyers and will stress to Injen that a system for the 330 should be manufactured.


-Straight up, this intake system is currently the best system on the market for 323,325,328 models. Featuring a superior build quality, throttle response and power gains in both horsepower and torque.

-This system includes the following: Aluminum upper intake boot, Heat-Shield, Intake Pipe, High Performance Air Filter, All the needed Hardware, Detailed installation Manual and an HID Ballast Relocation Kit (if needed)

-Replaces your flimsy rubber intake boot with an aluminum intake tube, providing more consistent air flow

-A heat shield is included to block out engine heat

-The air filter is located outside of the engine compartment, truly providing cold air

-Maximum power gains with the race grade Tube Style construction

-Available in 2 finishes, polished aluminum (seen above) or a sleek glossy black finish

-Made in the U.S.A.

HydroShield Pre-Filter

Injen Technology's HYDRO-SHIELD PRE-FILTERS are a race proven material manufactured from highly durable polyester. Uniform micron openings allow the filtering of debris .005" or larger. The HYDRO-SHIELD PRE-FILTERS are factory treated using an embedded hydrophobic process, which offers consistent airflow, water repellency and maintains horsepower gains.


-Keeps the air filter free of debris and unwanted particles

-Easy installation, slips right over the air filter

-Increases the air filter's life

-Doesn't sacrifice horsepower or torque

-Available in 3 colors: Black, Blue and Red
