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 46-39115 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 46-39115 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.
WARNING: This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm. For more information go to www.P65Warnings.ca.gov.
