Throttle Body Spacers

Name: Throttle Body Spacers | Air Intake Enhancers & Flow Boosters - Frigate
Price: 249.00 USD
Availability: InStock
Rating: 5 (837 reviews)

Throttle body spacers alter the intake tract geometry by adding a calibrated plenum extension, which reshapes the pressure wave dynamics as air flows toward the combustion chamber. This adjustment in runner length and volume helps reduce boundary layer separation and flow stagnation near the throttle plate.

Material Specification

6061-T6 Aluminum (Standard), Phenolic Resin (Heat Barrier), or Stainless Steel (304) (High-Temp)

Thickness

5mm – 25mm (Customizable for velocity stack effects)

Bore Diameter/Shape

50mm – 100mm (Matches throttle body ID; Optional tapered/venturi design)

Bolt Pattern Compatibility

4-bolt (70mm/80mm VW/Audi), 6-bolt (LS/LT), or OEM-specific (e.g., Toyota 4A-GE)

Gasket Surface Finish & Flatness

Ra 3.2 µm (CNC-machined); ±0.05mm flatness

Product Description

The improved airflow results in a more uniform velocity profile across the intake manifold. This promotes consistent cylinder filling and helps correct cylinder-to-cylinder air distribution imbalances, especially during transitional throttle conditions, enhancing throttle response and overall engine efficiency.

Airflow Design

Straight bore or Helix/rifled (Turbulence reduction)

Overall Dimensions & Clearance

+2mm OD vs. throttle body (Clearance for phenolic expansion); Hood clearance tested

Heat Transfer Properties

Phenolic – Reduces IAT by 10–15°C; Aluminum – Anodized for heat dissipation

Corrosion Resistance/Coating

Hard Anodized (Aluminum), Nickel Plating (Steel), or Chemical-Resistant Polymer (Phenolic)

Certification Standards

ISO 9001, SAE J1545 (Engine dress components), RoHS Compliant

Technical Advantages

By increasing the available intake volume immediately upstream of the throttle body, spacers promote enhanced air-fuel mixture homogenization. The additional plenum space allows for improved atomization of fuel droplets, especially in port-injected and throttle body injection systems. This effect can reduce cyclic variation in combustion, lower the incidence of partial misfire, and support more stable ignition timing under varying load conditions. Improved mixture preparation directly correlates with reduced hydrocarbon emissions and smoother engine operation.

The introduction of a throttle body spacers modifies the resonance characteristics of the intake tract, effectively tuning the system for improved charge ram effect at specific engine speeds. This tuning can shift the torque peak lower in the RPM range, benefiting drivability and load response, particularly in naturally aspirated engines. Enhanced volumetric efficiency at mid-range RPMs is achieved through the constructive interference of pressure waves, which increases the mass of air inducted per cycle without requiring forced induction or extensive hardware changes.

Industry Applications

Automotive Powertrain Enhancement

Used in gasoline and diesel engines to optimize intake airflow, supporting improved combustion efficiency and torque across variable operating conditions.

Commercial Fleet Vehicles

Applied to delivery trucks and vans to improve fuel atomization, resulting in more consistent power delivery and potential fuel economy gains during frequent stop-start cycles.

Off-Highway and Agricultural Equipment

Integrated into tractors and construction machinery to stabilize intake temperature and reduce heat transfer, supporting reliable engine operation under high-load environments.

Motorsport and Performance Tuning

Implemented in racing vehicles to fine-tune intake runner length, maximizing volumetric efficiency and throttle response at specific RPM ranges for competitive advantage.

Aftermarket Performance Upgrades

Installed by automotive enthusiasts and workshops to address intake manifold limitations, enabling measurable improvements in horsepower and torque without major engine modifications.

Emissions Control Systems

Utilized in engines requiring precise air-fuel mixture control, enhancing atomization and potentially reducing unburned hydrocarbons in exhaust output.

Integration with Engine Control Strategies

Modern engine management systems rely on precise airflow measurements for fuel and ignition mapping. Throttle body spacers can impact the airflow signal received by mass airflow sensors and manifold absolute pressure sensors. Careful calibration ensures that sensor readings remain within the expected range, preserving closed-loop control accuracy.

High-grade aluminum alloys are typically selected for spacer construction to balance structural rigidity with thermal conductivity. The spacer acts as a thermal break between the throttle body and intake manifold, which can reduce heat transfer to the incoming air charge.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How do FEM simulations prevent distortion in CNC-machined parts during transport?

Frigate employs Finite Element Method (FEM) simulations to identify stress concentration points and optimal load paths in precision components. This informs custom lifting fixtures and packaging designs that distribute mechanical stresses away from critical tolerances. By isolating vibration-prone areas and using dynamic load modeling, dimensional stability is maintained within ±0.002″ during transit.

What sensor architecture enables real-time thermal monitoring in intelligent busbars?

Sensor Intelligent Busbars integrate embedded thermocouples and fiber Bragg grating (FBG) sensors at nodal junctions, sampling at 100 Hz. Data is processed through edge-computing modules to detect thermal anomalies exceeding 5°C above ambient baseline. This triggers adaptive load balancing to prevent insulator degradation while maintaining ±1% current distribution accuracy.

How does Frigate’s predictive maintenance model detect bearing failures in rotating machinery?

The system analyzes vibration spectra using machine learning classifiers trained on failure modes like inner race spalling or cage deformation. High-frequency accelerometers (up to 50 kHz) capture time-domain waveforms, while envelope detection isolates early-stage fatigue signatures. Remaining Useful Life (RUL) predictions achieve 92% accuracy within 200-hour windows.

What prevents electrostatic discharge in Frigate’s cleanroom packaging protocols?

Conductive carbon-loaded polypropylene trays with surface resistivity <10^4 Ω/sq ground parts during handling. Ionized air curtains at packing stations neutralize static charges to ±50 V, verified by non-contact voltmeters. RFID tags with ESD-safe adhesives maintain Faraday cage integrity throughout logistics chains.

How are IoT environmental sensors calibrated for humidity control in transit?

Frigate uses NIST-traceable capacitive polymer sensors with ±1.5% RH accuracy across 10–90% ranges. Dual-wavelength optical mirrors provide in-situ calibration checks, while machine learning compensates for sensor drift using historical atmospheric pressure correlations. Data is logged at 5-minute intervals with GSM-based real-time alerts.
