What Is a Turbo Inlet Screen?

A turbo inlet screen installs directly onto the turbocharger compressor inlet.

Unlike a traditional air filter, it uses:

• Stainless steel mesh
• Open airflow design
• Minimal restriction construction

Its primary purpose is to block larger debris from entering the turbocharger while maintaining maximum airflow.

Important Disclaimer

A turbo inlet screen is not a full replacement for a conventional air filter.

Traditional filters provide significantly better protection against:

• Dust
• Dirt
• Fine particles
• Road contaminants

Turbo screens are generally best suited for:

• Race cars
• Track vehicles
• Dyno setups
• Tight engine bays
• Specialty turbo applications

Designed for Tight Engine Bays

One of the biggest advantages of the BoostCo screen is packaging.

Ideal Applications

• Turbo Honda builds
• LS turbo swaps
• Nissan drift cars
• BMW turbo conversions
• Custom race vehicles

When a traditional cone filter simply won’t fit, a compact screen can become the only realistic option.

4-Inch Inlet Compatibility

Inlet Size

• 4-inch turbo inlet

This makes it compatible with many larger-frame turbochargers commonly found on:

• 500+ HP street cars
• Drag builds
• Time attack vehicles
• High-boost applications

Always verify your compressor inlet dimensions before ordering.

CNC-Machined 6061 Aluminum Construction

The housing is manufactured from:

Material

• 6061 Aluminum

Benefits include:

• Lightweight construction
• Corrosion resistance
• Excellent durability
• Precision fitment

The CNC-machined body gives the screen a premium appearance while maintaining strength under demanding conditions.

Stainless Steel Mesh Protection

The screen utilizes:

Mesh Material

• Stainless Steel

Benefits include:

• Corrosion resistance
• Strength
• Long service life
• Debris protection

The mesh helps prevent larger foreign objects from contacting the compressor wheel.

Rated for High-Boost Applications

According to the manufacturer:

Pressure Rating

• 200 PSI

While most turbocharged street vehicles will never approach that level of boost pressure, the rating demonstrates the robustness of the design.

The construction is intended to withstand:

• High vibration
• Extreme temperatures
• Aggressive driving conditions

Improved Turbo Sound

Many enthusiasts install inlet screens specifically for the sound.

Compared to traditional cone filters, users often notice:

Louder Compressor Noise

Turbo spool becomes more noticeable.

Increased Induction Sound

The turbocharger can be heard more clearly.

Enhanced Blow-Off Valve Acoustics

Pressure release sounds become more pronounced.

For some enthusiasts, hearing the turbo is half the fun.

Compact One-Piece Design

The screen features a one-piece construction that helps provide:

• Easy installation
• Reduced weight
• Improved durability
• Minimal packaging requirements

The compact profile makes it ideal for vehicles where every inch matters.

Multiple Anodized Colors

Available finishes include:

• Black
• Red
• Blue
• Gold
• Purple

The purple version is particularly popular among enthusiasts looking to add a unique visual touch to their engine bay.

Pros and Cons

Pros

• Extremely compact design
• Fits tight engine bays
• CNC-machined aluminum construction
• Stainless steel mesh
• Lightweight
• Improved turbo sound
• Multiple color options
• Suitable for large turbo applications

Cons

• Not a substitute for a traditional air filter
• Limited protection against fine dust

Frequently Asked Questions

Is a turbo screen better than a cone filter?

No. A cone filter provides significantly better filtration. A turbo screen prioritizes airflow and packaging.

Will it make my turbo louder?

Yes. Many users install turbo screens specifically to increase compressor and induction sound.

Is it safe for daily driving?

That depends on your environment. Vehicles frequently exposed to dust, dirt, and road debris generally benefit from a traditional air filter.

Why use a turbo screen?

Primarily for space savings, airflow, and turbocharger protection in applications where a conventional filter cannot fit.

Final Thoughts

The BoostCo 4-Inch Turbo Inlet Screen fills an important niche in the performance world. For race cars, high-horsepower builds, and cramped engine bays where a traditional filter simply won’t fit, it offers basic compressor protection while maximizing airflow and turbo sound.

Just remember that a turbo screen is a protective guard—not a true filtration system. It’s perfect for the right application, but choosing one should be based on your build goals, environment, and willingness to trade filtration for packaging and airflow.

Because sometimes the biggest challenge in a turbo build isn’t making more boost—it’s finding somewhere to put all the parts.

🧱 Rock-Cast Construction CNC-machined 6061 aluminum + stainless mesh = a clear out guard that may take a beating and stay flowing.
🎯 Fits Where Others Won’t Designed to dominate tight engine bays with out sacrificing airflow or taste.
🟣 Color-Matched Performance Make your bay pop—choose between Black, Red, Blue, Gold, or Purple anodized finishes.
