Relatively good fit for an aftermarket part. Due to the large diameter, it rubs against the frame gussets and the airbox has to be opened up about an 1/8" per side as mentioned in the ad when I bought it. Does allow to get more air in without losing your airbox though. I accompanied this with the sprint airfilter for maximum flow and retaining all stock mounting bolts. Would recommend this product. Nothing is perfect, so I gave it a 4.
Decha Performance Intake Tube for the 2022 Honda Grom 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, and the other fits the 2019+ CRF110
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.
Pair this hose with the TST Worx Airbox lid cover for even more performance!
