Frequently Asked Questions

Will this require a tune after installation?

A larger throttle body alone typically does not require a tune on naturally aspirated engines. On forced induction or highly modified engines, updating the throttle body airflow calibration with a tune will maximize gains.

How much power gain can I expect?

A larger bore throttle body removes a flow restriction that matters most at high RPM and under boost. Gains compounded with an intake and exhaust are more significant than any single component alone.

Does this affect idle quality?

In most cases, no. A direct-fit high-flow throttle body maintains the factory idle air control system. Allow the ECU time to relearn idle parameters after installation. If idle quality issues arise, check for vacuum leaks at all manifold and spacer joints before drawing other conclusions.

Is this reversible?

Yes. This throttle body reinstalls using the same mounting hardware as the factory unit. The original can be stored and reinstalled at any time.

Does this work with my cold air intake?

Yes. The 46-39111 is fully compatible with aftermarket cold air intakes and other intake system modifications. Running a complete intake system with this high-flow throttle body delivers compounding airflow improvements.

Will this void my factory warranty?

Under the Magnuson-Moss Warranty Act, a dealer cannot void your factory warranty solely because you installed an aftermarket high-flow throttle body. They must demonstrate a direct causal link to any specific failure. Remove the 46-39111 before any dealer service visit if you prefer not to discuss it.

What is the warranty on this product?

aFe Power provides a limited manufacturer warranty covering defects in materials and workmanship. Contact aFe Power or us for current warranty terms and coverage specifics.

Are any gaskets included?

A factory-compatible intake gasket is included with the throttle body. Always use a fresh gasket at installation to ensure a leak-free seal.

Installation Overview

  1. Disconnect the negative battery terminal and allow the engine to cool
  2. Remove the intake tube connected to the throttle body inlet
  3. Disconnect the TPS sensor connector and IAC connections from the factory throttle body
  4. Remove the four throttle body mounting bolts and set the factory unit aside
  5. Install the new throttle body with a fresh gasket and torque all bolts to factory specification
  6. Transfer the TPS sensor and IAC connectors to the new unit
  7. Reconnect all intake plumbing and vacuum lines
  8. Reconnect the battery and start the engine to confirm normal idle
  9. Allow the ECU to complete an idle relearn cycle before performing a WOT test
