Swapping the restrictive factory airbox for a K&N Typhoon intake on a 2002–2006 Toyota Camry 2.4-liter four-cylinder changes how the engine takes in air. The kit uses a mandrel-bent aluminum intake tube and an oversized, washable oiled-cotton filter, the RU-4960 replacement element, so the filter can be cleaned and reused rather than swapped out like a paper element. The manufacturer gives an estimated gain of 6.4 HP at 5,600 RPM, which should be read as an estimate, not a guaranteed output.
Against a cheaper universal tube or a plastic drop-in filter, the Typhoon's smoother tube is built to reduce airflow restriction between the filter and the throttle body, and the reusable cotton element avoids recurring filter purchases. Buyers should understand the trade-off: oiled cotton needs periodic cleaning and re-oiling, and it does not filter the way a paper element does. Search terms this kit targets include K&N 69-8609TTK, Camry 2.4 cold air intake, 69 Series Typhoon intake, and RU-4960 filter.
