ALTA Cold Air Intakes reduce inlet air temperatures creating a cooler and more dense air charge, increasing horsepower and torque.

Cold Air Box

The ALTA Cold Air Box is formed from laser cut aluminum sheet metal then CNC bent to perfection. Then finished in a rich black texture powdercoating for long term protection and an O.E.M. look. Our air box seals to the underside of the hood preventing under-hood heat from entering the intake air stream.


With an ALTA intake system, your car will make a throaty, deep tone on throttle that is undeniably modified. You will be able to hear your supercharger whining, both stock and aftermarket.

Foam Filter

Our high-flow foam filter reduces intake restriction and increases the surface area from which the engine can ingest clean air. Unlike cotton and gauze type filters, foam filters allow for multi-layer filtration. The ALTA foam based filter will trap dirt within the filter at many different levels. This allows for better particulate restriction and will not reduce HP as the filter gets dirty. » Learn More

Intake Tube

The ALTA Inlet Hose connects the air box to the throttle body. With a mirror smooth finish inside and out, the silicone hose promotes increased air velocity traveling to the engine. Unlike the corrugated and ribbed factory inlet hose, turbulence is eliminated. Additionally, the ALTA Inlet Hose has a larger inside diameter to support the needs of your supercharger at all boost levels.


ALTA is the only producer of a cold air intake system for R53 MINIs that truly provides a steady supply of cool fresh air! Thanks to our uniquely designed air box and smooth black silicone inlet hose, the ALTA Cold Air Intake has proven a 10-12 WHP gain many times over. Check out the DYNO CHARTS tab above for more details.

Filter Tech

ALTA Intake Filter elements use open cell foam to capture dust and dirt. Washable and reusable, ALTA foam filter elements extend the life of your vehicle. Foam filter elements offer superior performance with minimal airflow restriction and amazing dust holding capacity.


Powdercoated for protection against the elements, the textured finish will look awesome for years to come. The ALTA Cold Air Intake System for R53 6-speed manual is available in black or red texture powdercoating.

Cold Air Intake on MCS

This is the first and original test we did on our stock 02 Mini Cooper S, where we did back to back dyno runs proving the intake makes 10WHP.

Dyno Chart

Cold Air Intake w/ 15% Pulley on MCS

Here is a test done on our shop MCS which had a 15% Supercharger pulley installed. You can see that the increases are even greater if you have a smaller supercharger pulley.

Dyno Chart

Cold Air Intake on Euro MCS

Here is another test given to us by customer of ours. This is also from a stock MCS where nothing was done between runs but changing out the stock intake to an ALTA complete cold air intake.

Dyno Chart

ALTA CAI vs. GP/JCW Intake

Most customers feel the JCW intake is just as good and makes the same power as the ALTA Cold Air Intake, but here is proof the ALTA makes more power. The 6 Wheel HP more and 6ft-lbs really shows that the more expensive JCW intake isn't worth upgrading to. Plus you get all the cool sounds of the Supercharger with our intake.

ALTA CAI vs. The Competition

This is an independent test done in a public forum online. This test compared all the popular intakes at the time and you will see that the ALTA was the one who came out on top.
