Solving the Limits of Factory Fuel Systems

As power increases, factory fuel systems often struggle to keep up with demand—especially on high-boost or ethanol-based builds. Spool Performance addresses this issue with a range of advanced fueling upgrades.

Key product categories include:

• High-pressure fuel pumps (HPFPs) for increased fuel delivery
• Low-pressure fuel pump (LPFP) upgrades
• Auxiliary fueling systems for high-horsepower builds
• Fuel pressure regulators and filtration systems

These components are designed to maintain stable fuel pressure and delivery, which is critical for both performance and engine safety.

Turbo Systems and High-Performance Hardware

Beyond fueling, Spool Performance also develops turbocharger systems and performance hardware designed to maximize engine output.

Their lineup includes:

• Billet turbo kits and manifolds engineered for high boost
• Performance downpipes and exhaust components
• Transmission and drivetrain upgrades
• Engine hardware for high-power applications

Many of these components are CNC-machined and engineered to withstand extreme heat and pressure while maintaining reliability.

Innovative Ethanol Monitoring Solutions

As ethanol fuels (such as E85 blends) become increasingly popular in performance builds, accurate fuel monitoring becomes essential. Spool Performance offers wireless ethanol content monitoring kits that allow drivers to track ethanol levels in real time.

These systems help eliminate guesswork and ensure the engine is running the correct fuel mixture—especially important for tuned vehicles running flex fuel setups.

Engineering-Driven Development Process

Spool Performance places a strong emphasis on engineering and product development. Each component goes through a detailed process that includes:

• CAD design and prototyping
• Computational analysis and testing
• Real-world validation across different environments
• Global beta testing for reliability

This approach ensures that every product is tested for fitment, durability, and performance before reaching customers.
