Description

The CTS Turbo Air Filter is a universal 4-inch cone filter engineered with a tapered design, allowing it to fit efficiently in constricted engine bays. It features a 4.0-inch inlet, measures 8.75 inches long, and is 6.0 inches wide, making it a versatile component for various intake setups. The filter includes a stainless steel clamp for a secure and reliable connection. Originally developed for use in CTS Turbo's MK4 and MK5 R32 big turbo kits, this air filter is also an excellent choice for custom big turbo builds and other aftermarket intake systems requiring a 4-inch inlet. Its robust construction and universal design make it a practical replacement part, contributing to optimal airflow and engine performance. Key product details include its 4.0" inlet, 8.75" length, and 6.0" width.
