The K&N 69-2541TB is a blue Typhoon cold air intake for the 2003 Chrysler PT Cruiser GT. K&N describes it as a free-flowing, mandrel-bent aluminum tube system designed to fit some Chrysler PT Cruiser models. The stock airbox and intake housing come out, and a rubber-topped cotton gauze filter sits in the old airbox space. The kit replaces the entire factory air intake system and uses a washable, reusable lifetime air filter.
Against stock, the appeal is measurable airflow and a filter you never have to replace. The manufacturer's estimate is 11.05 HP @ 4508 RPM, and it claims improved throttle response and engine sound. Service intervals stretch up to 100,000 miles before service is required (depending on driving conditions). Owners on user forums describe the 2004 GT's 2.4 engine as turbocharged, so confirm the fitment against your exact engine and model year before ordering.
Yes. The manufacturer says the kit replaces the entire factory air intake system, and its high-flow filter installs into the space the previous airbox occupied.
The manufacturer estimates a gain of 11.05 HP at 4508 RPM. Treat that as an estimate rather than a guaranteed figure, and note that the manufacturer's public listing does not confirm a torque figure.
The manufacturer rates the filter for up to 100,000 miles before service is required, depending on driving conditions. The filter is washable and reusable.
The manufacturer says this kit usually installs in 90 minutes or less using the factory mounting points, which makes it a reasonable weekend job for a driver with basic hand tools. K&N's Typhoon instruction sheets for other models list a ratchet, extension, 10mm and 13mm sockets, and a flat blade screwdriver, so plan on something similar. Disconnect the negative battery cable first, but write down radio presets and other memory settings, since disconnecting the battery erases them and some radios ask for an anti-theft code afterward. Install the mass air sensor into the new tube, and use every supplied clamp and coupler, because K&N warns that skipping the provided hardware can damage the intake tube, throttle body, or engine. K&N also recommends keeping the factory intake rather than discarding it.
