Install was super simple. The item comes with a rubber insert for smaller diameter steering wheels. I did not need the rubber insert/spacer on my factory BX2370 steering wheel. I did take special care to position the spinner on the wheel exactly where I thought it would be best for my situation. Turns out, that the steering wheel on my BX2370 does not return to the original position. In other words, I installed the spinner on the bottom of the steering wheel when the front tires were in a straight ahead direction(not turned). After driving the tractor a bit, the spinner was at the top of the wheel while moving forward. A little more driving put the spinner at the side. Install the spinner at the most convenient location for installation as the position of it will change with tractor use.
While the ad stated this item was a match and even gave the exact part number I needed, this filter was half the height of the original. While I am not near the lawn mower now, the original filter was roughly 4 or 5 inches tall. This replacement is half that. There is a large gap between the top of the filter and the metal air filter hold down clips on the mower. Other than that, the air filter will work as it fits snugly onto the carb opening which is the only thing holding the filter to the engine. I'll use it for the rest of the season and then change it out with one of the proper size. Quality wise, it is top notch with no other issues.
