27mm Throttle Body / Intake Manifold Kit 2022+ Honda Grom / Monkey

Upgrade the stock 24mm throttle body and cast manifold with a ported 26mm or 27mm throttle body, along with the CJR ported manifold. Our ported manifold is designed to be used with either a stock or port matched race head.

The 26mm throttle body may be used with your stock unmodified OEM intake manifold for an average 3-4% increase across the entire RPM range - No additional tune upgrade is required when moving from the OEM 24mm, bolt on and enjoy the additional power! 

The 27mm throttle body will require the CJR ported manifold and the combination makes for an average 7-8% increase in power through the midrange and top end while on the stock cylinder head. On average we see a 1hp increase when combined with intake/exhaust/camshaft/tune Additional tune upgrade is required for the combination upgrade.

*Note - Requires swapping OEM throttle cable bracket onto the new throttle body
**Note - No EVAP nipple is located on the new manifold. 
***Note - Cam reel does have a slightly different orientation, does not affect performance or install. A throttle cable adjustment may be required.
****Note - Return cable is optional to use OEM or delete for racing applications.
