Skunk2’s Alpha Series Throttle Body is designed to be used with Skunk2’s Pro Series Intake Manifolds as well as OEM and other aftermarket intake manifolds for bolt-on horsepower and torque gains by maximizing engine airflow, all at a competitive price.A larger throttle body is key to producing additional power throughout the powerband on modified engines with increased airflow demands and the Skunk2’s 70mm Alpha Series Throttle Body delivers! Sealed ball bearings, a precision machined throttle plate and a honed oversized bore insures smooth operation on the most aggressive naturally aspirated and forced induction applications.Features:Precision Die-Cast AluminumFine Shot-Blasted Surface FinishPrecision Machined Brass Throttle PlateCompatible w/ OEM Throttle CableSealed Ball Bearings for Smooth OperationIncludes Throttle Body Gasket and HardwareIdle Adjustment Screws for Fine Tuning** NOTE: Throttle Body requires proper TPS adjustment after install.

Not compatible with B18C GS-R intake manifold. Not compatible with D Series engines featuring down-flow intake manifolds.

Review: Excellent Quality - This thing in conjunction with the intake manifold definitely woke up the throttle response. 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.
Review: Nice parts that fit . - Skunk2 Products always look so nice and they fit perfectly!!!

### ⭐⭐⭐⭐⭐ 70mm great quality throttle body
*by B***6 on July 27, 2023*

only flaw it had which was a simple to adjust. Was the wing nut for the throttle. My car usually idles at 950 - 1000 rpms, after installing this throttle body I was roughly at 1200rpms full operating temp. so after loosening the wing nut 2 turns it dropped back to 950 ish - 1000 again , other than that works amazing with a noticeable difference !! cant wait to grab the stage 2 tuner series camshaft and cam gear from skunk2 !!
