4in Inlet Cone Filter 8.75 in Long

The SPECTRE 4in Inlet Cone Filter is a universal reusable air intake component designed for automotive enthusiasts looking to enhance engine performance and achieve long-term cost savings. This filter is ideal for those building custom intake manifolds, upgrading classic engines, or fine-tuning modified vehicles.

With a 4-inch inlet diameter, this cone filter efficiently delivers clean air to your carburetor or throttle body, significantly improving airflow compared to traditional paper filters. Its conical design maximizes filter media exposure, allowing for longer service intervals and reduced backpressure, which is crucial for naturally aspirated and modified engines.

Mechanics and engine builders appreciate the SPECTRE cone filter for its compatibility with custom intake applications where OEM airboxes may not fit. Weighing 2.05 pounds, it is compact enough to fit in tight engine compartments, making it a preferred choice for street rods, vintage restorations, and performance swaps.
