Tepeng Air Intake Air Filter System Compatible with 2013-2020 Honda Grom 125 MSX125

The mounting holes for the sensor screws are not the correct depth or properly tapped, schwarf and lose debris waiting to fall into the engine. Avoid and go chimera or 1 that's not trash, unusable, zero customer service.

Not bad for the price. The Chimera is better quality but barely. I would buy this again for another grom I get in the future. Only thing is, this kit doesn’t come with screws so you will need to cut down the stock screws from your AF sensor. Cut off maybe 1/4” or more. The threads also are a bit more aggressive but they work with the stock screws.

Does fit z125 pro really gave it a little more kick . Easy to install. Wish it would’ve came with instructions

This takes some knowledge. It installs on right hand side of bike, does not wrap around to left hand side of bike. you need to get bolts for A/F sensor, factory does not fit. Clean up holes and welds, like others mine had a few barbs, not a big issue.

I installed this on my 2015 Grom and am overall happy with it but there are reasons why it is less expensive than other similar products.With this there is a noticeable power increase in the high rpm range making the riding much more enjoyable. There is also a noticeable increase in sound under moderate to heavy throttle.As others have pointed out, you will need to source your own hardware for holding the sensor into the intake as the stock screws are meant to go into plastic, not metal. Also there was a large metal chip where the sensor hole was drilled and was never cleaned out. I ended up breaking it off with a screwdriver and filing down the remaining bits.The only other downside I've noticed is that this intake system is much more susceptible to being fouled from rain water splashed off the front tire than the stock intake system is. For me, this resulted in a lack of power and engine surging under heavy acceleration until the filter dried out. The fix for that is apparently to install a pre-filter over the filter element. I did this but have not had the chance to test it out.Overall if I had the chance to purchase this again, I would consider it but might end up going with another intake system.

Had to HEAVILY modify it to make it work, had to weld a sensor door shut and cap off a vacuum line tube entry on the intake tube, not happy. I would rather scissor my brother.
