## Overview

The Spectre Performance SPE-9741 Intake Coupler is a vehicle-specific reducer that connects 4" and 3.5" diameter intake tubes. Made from durable PVC available in red or black, it includes two stainless steel worm gear clamps for a secure fit. Ideal for naturally aspirated engines, this coupler delivers reliable, vibration-resistant performance favored by automotive enthusiasts.

## Description

Spectre’s Intake Coupler Reducer is designed to connect any 4 inch outside diameter component or air intake tube with a 3 1/2 inch outside diameter component or intake tube. This intake coupler is available in both red and black PVC and comes complete with 2 stainless steel worm gear hose clamps. This product is not recommended for turbo-charged/super-charged engines.

Review: excellent product and price point - Needed replacement for my 06 Avalanche, using K&M air filter intake tube. Couldn't find replacement from any part stores, NAPA wanted $65 for 1 ft piece of rubber tube (that i would have to cut down, and didnt include pipeclamps). This adapter came with 2 hose clamps and worked good on my truck, a bargain, will probably order another one to have as a spare
Review: Perfect for my 2014 Mustang - I recently put a BOSS 302 intake manifold in my 2014 Mustang 5.0, and I added an Accufab throttle body along with a JLT CAI. I needed a coupling like this in order to connect the TB and CAI of course, and they're two different diameters. This did the trick and everything is connected all snug! Even held up through DynoTune and didn't break loose or anything. Great quality, would recommend.
