Huge improvement over 64mm. Beautifully made. To the rookies out there hellbent on modding their Hondas: I recommend an AFR wideband gauge at the LEAST, and ideally a Hondata ECU BEFORE upgrading anything that messes with air or fuel. ## Frequently Bought Together - Skunk2 Racing 309-05-1050 Alpha Series Silver 70mm Throttle Body for Honda B, D, H, F-Series Engines - Skunk2 (372-05-0275) Thermal Intake Manifold Gasket for Honda D-Series Engine - Skunk2 Racing 307-05-0265 Pro Series Black Intake Manifold for Honda D-Series Engines --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/264898961-309-05-1050-alpha-series-silver-70mm-throttle-body-honda](https://www.desertcart.us/products/264898961-309-05-1050-alpha-series-silver-70mm-throttle-body-honda) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
