How to replace air intakes on Acura ILX
An air intakes system can modify the air cooling system of the engine. It can enhance your engine power and can be helpful for your long-lasting service of engine performances. It can convert the compressed, super-heated, boosted intake air leaving the compressor outlet of the turbo into cooler, denser oxygen for the engine to ingest. Here are given some steps for installing the air intake in your car.
Step 1- Remove the three 10mm bolts holding the throttle body cover.
Step 2- Loosen the factory hose clamp on the throttle body, and the 3/4" idle air bypass hose and the 5/8" breather hose. On some 04-05 models the IAB is not present.
Step 3- Unplug the IAT sensor and remove the intake duct from the engine. On some 04-05 models the IAT sensor is not present.
Step 4- Lift air filter housing by pulling straight up it is held in place with 2 rubber grommets. On the backside of the canister is the MAF harness. Unplug the harness from the vehicle and remove it. Save items for future use if needed.

Step 6- Install the hump coupler and clamps on the air filter housing and install the 3" straight coupler and clamp on the throttle body.
Step 7- Install the rubber grommet into the IAT sensor location. Reinstall the IAT sensor and reconnect the harness. At this time plug the MAF sensor into the harness and secure the harness on the side of the housing with the included mounting holes. If you do not have an IAT sensor use the provided grommet and cap to seal the opening.
