Awesome quality, best made product on the market. Fits perfect without running into the throttle body.

One of the best intake setups you can get for the sxr 1500. We have tested numerous setups and we chose the macsboost filter setup! Quality filter, highly recommended
I was skeptical that a $139 mod would really do much for the performance of my SXR. I relocated the warning lights to dash of the ski and needed more room for what the stock airbox allowed, so I purchased this filter. Improvement in power throughout the entire RPM range. Most significant improvement was mid to top end. The engine pulled harder through the midrange and and got to a higher top speed faster. Well worth the money and the installation took less than 15 minutes.

Dollar the best intake for the 1500 ski. We use it on all our builds.

I have an SXR 1500 I took my airbox off put on a Mac boost filter and a breather filter and holy crap it …woke my ski up, Snappier response, faster out of the hole, Quicker response on the fly mid track on and off the throttle snappier, I could not believe the difference it made, If you want to improve your ski I will definitely buy one of these filters, 5 star for sure
