Decha Performance 2022+ Honda Monkey Stealth Intake Tube

$80.00
by Decha Performance
Include 42mm install tool

Decha Performance Intake Tube for the 2022-2024 Honda Monkey Stock Airbox

  • 38mm internal diameter
  • OEM hose ribbed synthetic hose material
  • Fits stock airbox (requires airbox modification
  • Two airbox notches, one fits the 2022+ Honda Grom/Monkey, and the other fits the 2019+ CRF110
  • Gains of nearly 2hp at 9,000rpm

The Decha Performance intake tube replaces the hose that connects your stock airbox to the throttle body. By increasing the internal diameter throughout, you can now have a stock airbox that performs like an aftermarket intake! Using the stock airbox keeps noise levels down and also retains the oem mounts for your side fairings (no more floppy fairings!). The stock airbox is also favored by trail and off-road riders because it has superior water and mud resistance compared to an open filter. 

Optional 42mm stepper bit to help install. Simply use this bit and drill the airbox hole until the entire bit passes through.

**TST Worx lid is NOT compatible with the Monkey Airbox.

Decha Stealtch Intake/ DHM Intake + Exhaust tuned ECU

10/10 would recommend to anyone with a Honda Grom. I purchased the stealth intake and flash tuned ECU from DHM for my wife’s 2025 Honda Grom and couldn’t be happier with the performance upgrade we got out of it. We waited till we put about 2200 miles on a stock everything before doing the upgrades. Bone stock with no power upgrades or body modifications, originally we could get it to hit 71 mph max going down hill and 56 on a flat straight road, after doing the power upgrades as well as some body mods like a 12 bar that added to its weight, the Grom now has the ability to do 83 MPH downhill and 74 MPH on a flat straight. 100% satisfaction from this customer and can guarantee I will be buying from here again.

Decha Monkey Intake Tube

Install was a breeze with the optional 42mm step bit. Get it if it's available. The tube went from chump to chimp. I wish I was able to attach photos so you can see the difference. Thanks DHM!
