Throttle Bodies for LS, Coyote, Hemi, K-Series, 2JZ, EJ Engine Builds

What This Collection Covers

This collection covers replacement and high-flow throttle bodies across domestic, import and late-model truck platforms. Bore sizes from compact 62mm units to 105mm race pieces let builders match airflow demand to the intake manifold, throttle control and ECU strategy.

Bore Size and Airflow

Throttle body bore size should suit the intake manifold opening, cylinder head combination and expected power level. An oversized body can complicate low-speed control if the rest of the intake system does not support the added airflow.

62mm to 105mm Options

Smaller units suit many street and compact-engine applications, while 90mm, 95mm, 102mm and 105mm units are common on large-displacement or boosted builds.

Drive-By-Wire and Cable Throttles

Electronic throttle bodies require compatible wiring, pedals, ECU calibration and connectors. Cable-driven units need the correct linkage and idle control provisions.

Electronic Control Compatibility

Confirm whether the engine management system supports the selected electronic throttle body and whether a matching adapter or harness is required.

Intake Manifold Matching

The throttle blade, bolt pattern and inlet diameter must match the manifold or adapter plate. A correctly matched transition reduces airflow disruption and gives the installer a dependable sealing surface.

Adapter Plates and Spacers

Adapter plates make it possible to pair certain throttle bodies and manifolds with different bolt patterns. Check thickness, port shape, gasket requirements and hood clearance.

Platform-Specific Performance

LS and LT builds, Coyote Mustangs, HEMI cars and trucks, K-series Hondas, Subaru EJ engines and import turbo builds all have distinct throttle layouts. Product filters help match the part to the engine family rather than selecting by bore size alone.

Street and Race Applications

Street builds often prioritize stable idle and OEM-style electronics, while race setups may prioritize maximum airflow, cable control and simplified plumbing.

Installation and Tuning

Throttle body upgrades can require calibration changes, relearns or idle adjustment. Confirm connector orientation, TPS and IAC provisions, intake tube size and available clearance before beginning installation.

Supporting Intake Parts

A matched air intake, intake manifold, fuel rail and engine calibration help the upgraded throttle body deliver consistent results.

How to Choose the Correct Part

• Confirm the engine family and exact intake manifold.
• Match the throttle body bore to the manifold opening.
• Verify cable or drive-by-wire operation.
• Check connector, TPS and idle air control compatibility.
• Confirm bolt pattern and gasket shape.

• Check ECU calibration and relearn requirements.
• Consider the intended power level and induction type.
• Review hood and accessory clearance.
• Add an adapter plate only when the application specifically supports it.

Common Questions

What throttle body size do I need?

Choose a bore size that matches the intake manifold, engine displacement, induction system and power goal rather than simply selecting the largest option.

Can I use a drive-by-wire throttle body on any engine?

No. Electronic throttle bodies require a compatible pedal, wiring, ECU control strategy and often a vehicle-specific harness.

Do throttle bodies require tuning?

Some upgrades require a calibration update, idle relearn or throttle relearn to operate correctly with the factory or aftermarket ECU.

What is a throttle body adapter plate?

An adapter plate changes the bolt pattern or port transition so a supported throttle body can mate to a different intake manifold.

Will a larger throttle body add power?

It can reduce a restriction when the manifold and engine can use additional airflow, but results depend on the complete combination.

Do cable and electronic throttle bodies interchange?

They generally do not interchange without the correct linkage, electronics, ECU support and application-specific conversion parts.

What is the difference between cast and billet throttle bodies?

Cast bodies are commonly used for OE-style replacements, while billet pieces are machined from solid material and often target performance or custom builds.

How do I match an intake tube to a throttle body?

Compare the throttle body inlet diameter and bead style with the coupler or intake tube, then verify available engine-bay clearance.

Are aftermarket throttle bodies street friendly?

Many direct-fit units are designed for street use, but stable operation depends on correct sizing, installation and electronic compatibility.

Can I use a throttle body with a stock manifold?

Some direct-fit throttle bodies work with stock manifolds, while other combinations need an adapter or an upgraded manifold.
