This is a cold air intake kit for the 2005-2006 Nissan Sentra with the 1.8L QG18DE engine. It replaces the factory airbox and baffled intake tube with a mandrel-bent aluminum pipe and a high-flow cone filter, which smooths airflow and pulls cooler air from outside the engine bay. The main gains are sharper throttle response and a louder induction note under hard acceleration; horsepower gains on this engine are modest. It suits Sentra owners who want better sound and a cleaner engine bay, not a big power jump. Compared with the stock setup it flows more freely, but it needs more filter maintenance and can be louder at cruise than a closed factory box.

Owners of the B15 Sentra 1.8L generally report sharper throttle response and a much louder intake sound after fitting this style of kit. Most criticism centers on modest real-world power gains and the extra filter upkeep.
This cold air intake replaces the factory airbox, resonator box and accordion intake tube on the 2005-2006 Nissan Sentra with the 1.8L QG18DE engine. It uses a mandrel-bent, polished chrome aluminum tube and a performance air filter. The tube gives the air a smoother path to the engine.
The system deletes the sound-deadening resonator box, which gives a deeper intake sound under heavy acceleration. It is engineered to maintain factory air/fuel ratios and does not require tuning.
It installs as a direct bolt-on replacement for the factory airbox. The factory Mass Air Flow (MAF) sensor transfers to the new intake. Handle the sensor carefully and seat its O-ring evenly. Disconnecting the negative battery terminal for 15 minutes during installation is recommended so the ECU can relearn the airflow parameters.
