Description
Product Overview
The Speed Dealer Customs Harley breather filter bolt is engineered for performance and durability. CNC‑machined from a solid billet of aerospace‑grade aluminum, the bolt offers exceptional strength while remaining lightweight. A premium black anodized finish protects the surface from corrosion, scratches, and the harsh elements encountered on the road. Stainless‑steel snap rings and a fine wire mesh seal provide a leak‑free connection, ensuring optimal airflow to the engine’s intake system.
Designed specifically for Harley‑Davidson Big Twin motorcycles produced from 1999 onward, this bolt matches the original specifications while delivering enhanced reliability. The bolt measures 3/8‑16 thread diameter and extends 3/4 inch in length, fitting seamlessly into the breather filter housing of Softail, Dynastar, Touring, and CVO models. It will not fit the EVO series, which uses a different mounting configuration.

Usage
Whether you are cruising on a long highway ride, navigating city traffic, or tackling a weekend ride‑along, the breather filter bolt plays a critical role in maintaining engine health. By securing the breather filter, it helps regulate pressure within the crankcase, preventing oil leaks and ensuring that the engine breathes efficiently. This is especially important for high‑performance riding where consistent airflow can affect power delivery and fuel economy.
The bolt’s robust construction makes it suitable for both daily commuting and aggressive riding styles. It can withstand vibration, temperature fluctuations, and exposure to road salt without compromising its integrity. Install the bolt during routine maintenance or as part of an upgrade package to improve the reliability of your Harley’s intake system.
