I focused on the Best Blox Racing throttle body listings for B/D/F/H- and K-series platforms, where fit and throttle size matter. With 68mm, 70mm, and 72mm options plus billet or cast aluminum, buyers are mainly balancing compatibility, material, and setup effort.
Use this review to separate what’s really different: 68mm vs 70mm vs 72mm, K-series vs B/D/H/F-series, and billet dual-pattern vs cast aluminum. I’ll also flag what’s included (like the gasket on the cast 70mm) since bundle details can affect total install friction.

What to Look For Before Buying
Buyers should prioritize the correct bore size for their engine. It is vital to check compatibility with the intake manifold. Ensure the throttle body supports the electronic drive-by-wire system.
Check Select the Correct Bore Size
Choose a size that matches your engine’s displacement. Larger bore sizes increase airflow but may require tuning. Stock applications often work best with stock or slightly larger diameters.
Value Verify Throttle Body Pattern
Check the throttle body pattern to match your manifold. Some engines require specific bolt patterns for a secure fit. Dual pattern options offer more flexibility for different setups.
Rating Assess Build Quality
Look for high-quality materials like billet aluminum. This ensures durability and resistance to corrosion. Polished finishes can enhance the appearance of the engine bay.
Verify Check Tuning Requirements
Verify if the unit requires a tune for optimal performance. Some units work well on stock ECU maps. Others need professional calibration for maximum gains.
Frequently Asked Questions
Does a throttle body increase horsepower?
Yes, a larger throttle body increases airflow. This can improve throttle response and power. However, gains depend on the engine and tuning.
Do I need to tune after installation?
Not always, but it is recommended. Stock ECU maps may not account for the new airflow. Tuning optimizes fuel and timing for best results.
What is the difference between DBW and cable?
DBW uses an electronic signal. Cable systems use a physical linkage. DBW offers smoother transitions and better integration with modern cars.
Can I install this myself?
Basic mechanical skills are required. The installation involves removing the old unit and bolting the new one in. Some steps may require lifting the car.
Which size is best for my car?
Check your stock throttle body size. Generally, going up 2-4mm is a safe upgrade. Consult a mechanic for specific engine recommendations.
🎯 Final Verdict
The Blox Racing K-Series 72mm Black Billet throttle body stands out as the top choice. It offers maximum airflow for K-series engines. It is perfect for serious performance builds. The 68mm Tuner Series is a great runner-up for B-series cars.
Ensure you match the size to your engine for the best results. Upgrade today for better airflow.
