The GR and GV WRX and STI share the same EJ25 turbo engine with the same intake problem: a restrictive paper panel filter inside a plastic airbox that limits airflow before the turbo even spools. This Air Intake Kit replaces the factory airbox with a mandrel-bent aluminum intake tube and a high-flow cone filter -- sharper throttle, faster spool, and the deep boxer induction note the factory spent serious money to suppress.

The GD WRX and STI's factory intake pulls air through a restrictive paper panel filter inside a plastic airbox that heat-soaks within minutes. On a tuned EJ20 or EJ25, the stock intake is the first bottleneck. This Air Intake Kit replaces the factory airbox with a mandrel-bent aluminum intake tube and a high-flow cone filter -- more air, sharper turbo spool, and a deeper boxer induction note.

The Evo X's 4B11T is a turbocharged engine that left the factory with an intake designed for Mitsubishi's NVH department, not its performance division. The stock airbox chokes airflow through a restrictive panel filter and a baffled intake tract. This Stock Location Intake Kit replaces the factory airbox with a high-flow cone filter and mandrel-bent aluminum intake tube -- same location, same mounting points, vastly more airflow.

"Unleash the full potential of your K20C1 engine with our High-Flow Cold Air Intake System, specifically precision-engineered for the 2022-2026 Honda Civic Type-R (FL5). While the factory induction system is designed for broad usability, it often restricts the breathing capacity needed for high-boost racing and performance driving. Our intake system replaces the factory air box with a high-volume flow path and an integrated thermal barrier, delivering a consistent stream of cooler, oxygen-rich air directly to the turbocharger. The result is instantaneous throttle response, significant gains in horsepower and torque, and the legendary induction roar that defines the Type-R pedigree."

4" Shorty Power Air Intake Kit specially designed for Sea-Doo jet skis, built with lightweight carbon fiber housing and high-flow air filter to boost intake airflow and engine throttle response.

This universal 4 inch titanium intake filter kit is engineered for all mainstream Sea Doo and Yamaha personal watercraft. Ultra-light titanium tubing cuts heat soak, the hydrophobic filter blocks seawater splashes, and it delivers snappier throttle response for daily cruising and competitive jet ski racing.

Our Power Filter Kit feeds your supercharged Sea-Doo engine a steady diet of cool air delivering greatly improved acceleration and rpm. Replaces restrictive stock air intake system with a high-volume, precision-formed air intake duct that attaches to the supercharger via a tapered adapter. Simple installation & quick removal allow easy access for engine maintenance. Includes water-repellent pre-filter.
