## Overview

The Spectre Performance SPE-9751 is a 4-inch air duct hose featuring a memory-flex design that retains custom bends, 41 inches of durable ducting, and dual-threaded rubber boot ends for secure, airtight connections. Ideal for creating custom cold air intake systems, it delivers reliable performance and professional-grade durability favored by automotive enthusiasts and restorers alike.

## Description

This Spectre air duct hose attaches directly to a 4 inch air box inlet, plenum, intake tube or mounting plate to bring cool air into the engine. All Spectre air intake components are designed and built using high quality materials and engineered for optimum fit and function.

Review: Works and looks great! - Used this on my 1962 Corvette resotomod for the fresh air intake. Easy to install and looks great!
Review: High quality hose and exactly what I needed. - High quality flex tubing. NOT dryer hose or remotely similar to it as a reviewer stated. Ends are a bit difficult to thread on the hose but once correctly installed provide a sealed connection. Add hose clamps to fasten it to your intake and whatever you are pulling air from and you are done. The strength of this product is quite apparent. You can form an S with the hose and it will retain its form while you hold it up. This hose was 41" stretched out before I divided it. I needed 2 hoses so I cut this into two and bought an extra set of couplers. Nice and worth the cost to me.

## Features

- Memory-flex design helps retain its position and bends
- Helpful for creating a custom intake system
- Can be used to bring cold air into the engine
- 41 inches of ducting and two threads on rubber boots

### ⭐⭐⭐⭐⭐ High quality hose and exactly what I needed.

High quality flex tubing. NOT dryer hose or remotely similar to it as a reviewer stated. Ends are a bit difficult to thread on the hose but once correctly installed provide a sealed connection.

### ⭐⭐⭐⭐ Easy install. Far better cost option than molded tunes.
*by S***T on September 10, 2025*

Fit perfectly, easy to shape and install. As a bonus it sounds good. Far better cost option than the molded intake tube. While yes the molded look far better but the crazy extra cost for me wasn't worth it. I simply wanted to loose the bulky factory intake. I left my stock air box as it is essentially a closed cold air intake anyways. Very pleased.
