Torque Solution 19mm Intake Manifold Spacer Black 2002-2014 WRX / 2004-2021 STI | CNC Billet Aluminum | Intake Manifold Spacer

Overview

The Torque Solution 19mm Intake Manifold Spacer is designed specifically for Subaru EJ engine platforms equipped with naturally aspirated (NA) or JDM long runner intake manifolds. This spacer provides the necessary clearance for AVCS solenoids or custom reversed intake manifold setups, making it an essential component for enthusiasts performing long runner intake manifold swaps on WRX, WRX STI, Legacy GT, and Forester XT models. By increasing the distance between the intake manifold and the cylinder head, it allows for improved fitment and easier installation of aftermarket or JDM intake manifolds without compromising sealing integrity.

Manufactured from CNC-machined 6061 billet aluminum and anodized for durability, this intake manifold spacer reflects Torque Solution’s commitment to precision engineering and quality materials. The inclusion of o-ring gaskets on both the top and bottom surfaces ensures a boost leak-free seal, eliminating the need for OEM gaskets and simplifying installation. The spacer’s 19mm thickness is carefully chosen to provide optimal clearance while maintaining proper airflow characteristics, supporting both naturally aspirated and forced induction setups.

For Subaru owners, this spacer offers a practical solution to common fitment challenges encountered during intake manifold swaps or custom engine builds. Its robust construction and comprehensive hardware kit make it a reliable upgrade that maintains factory-level sealing and enhances compatibility with a variety of intake configurations. Whether upgrading for performance or custom fabrication, this spacer helps maintain the integrity and efficiency of the intake system on popular Subaru EJ-powered models.

Installation & Compatibility

Installation of the Torque Solution 19mm Intake Manifold Spacer is straightforward for those with moderate mechanical experience and basic hand tools. The spacer bolts between the intake manifold and cylinder head, using the supplied hardware and o-ring gaskets to ensure a secure, leak-free seal. While the included hardware fits most NA and JDM long runner intake manifolds, some custom or non-standard setups may require sourcing longer bolts for the center fasteners. No special tools are required beyond standard hand tools, but care should be taken to torque bolts to manufacturer specifications to avoid leaks.

• Professional Installation: Recommended for first-time installers or custom applications
• Modifications Required: None for NA/JDM long runner manifolds; longer bolts may be needed for other intake types
• Verify Compatibility: Confirm fitment for your specific Subaru model year and intake manifold configuration
