The aFe POWER 87mm throttle body and adapter kit upgrades GM trucks and SUVs (2014–2023 V8 5.3L) by increasing inlet diameter over the stock 80mm unit. Billet 6061-T6 aluminum adapters are precision-machined and the serrated/swirl design promotes intake turbulence for improved fuel atomization. The direct bolt-on kit includes hardware and gaskets, plug‑and‑play electronics compatibility, and requires no tuning for basic installation.
