## Overview

The Spectre Performance 9781 is a flexible 4-inch 90-degree intake coupler made from durable PVC, designed to optimize airflow in tight engine spaces. It includes two stainless steel worm gear clamps for a secure connection and is highly rated for reliability in naturally aspirated engines, making it a top choice for professional and enthusiast builds.

## Description

This Spectre Intake Coupler is a 4 inch to 4 inch 90 degree elbow. It comes with two stainless steel worm gear hose clamps. Use it to connect any 4 inch outside diameter component or air intake tube to a 4 inch outside diameter component or intake tube. The coupler is not recommended for turbo-charged/supercharged engines.

Review: This is "not" hard plastic. - This elbow is "not" hard plastic. It is flexible material (rubber like) and fit and functioned just like we wanted. Used it to make our own cold air kit on an LS engine in a 1964 Chevy El Camino. The description states PVC and most think that is hard plastic, this is not. It is very flexible and can be trimmed if needed. I would not recommend using in boosted applications (per manufacture as well) as there apparently is not any reinforcement woven into the material.
Review: Perfect for tight spaces - This worked great for an LS-Swap in a small engine bay.
