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 !!
