Product Description

The K&N E‑1500 is a premium performance drop‑in air filter engineered specifically for classic GM V8 cars and trucks from 1968 through 1997. With its 11.875″ outside diameter and 3.438″ height, it fits large round factory air boxes used in many full‑size GM vehicles while delivering increased airflow and engine response compared to standard paper filter elements.

Ideal for enthusiasts restoring or maintaining older GM vehicles, the E‑1500 uses multi‑layer cotton gauze media that is washable and reusable—reducing long‑term cost and waste. Installation is simple: remove the stock element, inspect the housing and sealing surfaces, install the K&N E‑1500, and you’re ready to drive with enhanced performance and filtration.

Please note: This filter covers GM V8 cars & trucks through 1997 as listed. Fitment for 1998–2025 and newer platforms is **unconfirmed at time of listing** and must be verified per vehicle. Maintenance: clean and re‑oil following K&N’s instructions when the filter reaches ~75,000 miles (or sooner under dusty/off‑road conditions).
