Suzuki Boulevard 1500 Cruisers Get More Air From the K&N SU-1409 Air Filter

The substantial power plant on the Boulevard benefits from the airflow of the K&N SU-1409 filter

The big engine on the 1500cc Suzuki Boulevard power cruiser has gained the reputation for reliability and smooth power delivery. That 90-cubic-inch, 54-degree, liquid-cooled V-Twin engine features four-valves in each of its dual-sparkplug heads. Those two big 750cc cylinders are fed by 42mm Mikuni EFI throttle bodies with dual throttle valves.

Of course, engines pushing that much displacement need air and lots of it. The Suzuki Boulevard is especially receptive to the added airflow that K&N filter technology delivers. The K&N SU-1409 direct replacement air filter is just the prescription to open up the lungs on several Boulevard models produced from 2009 – 2017.

It’s pretty simple. More air to an engine greatly increases the potential for more power. Restrictive stock filters limit the air available to the fuel injection system which, in turn, limits the bike's performance potential. K&N has been producing and refining free-flowing filters for over four decades.

Performance gains that a rider can feel is what K&N is all about. One of our astute customers, Sherwin H. from Union City, Georgia, was effusive in praising what the SU-1409 did for his 2009 Suzuki Boulevard M90.

“I noticed it idles a whole lot smoother,” said Sherwin. “[It] pulls stronger from a dead stop. Downshifting and passing had definitely improved. Can't beat that formula - more air, more power. Very, very pleased with this product.”

Those real-world performance benefits don’t come at the expense of real-world engine protection. In K&N’s stringent testing, the SU-1409 filter achieved an estimated filter efficiency of almost 99.5% in both initial and overall performance. That amazing filtration efficiency is made more impressive when you combine it with the test-verified dirt holding capacity estimate of over 11 grams.

The benefits of the SU-1409 don’t stop with more power and great filtration. The filter is also easy to install and is extremely cost efficient over its guaranteed lifespan. Again, our happy customer, Sherwin, may have put it best.

“Considering the fact that a new regular filter for this bike is about $85 for a single use, highly restrictive filter, this is actually a great deal,” Sherwin said. “If you have ever changed the air filter on your bike then you will have absolutely no problems installing this filter. Just read the instructions and you will be very happy with how easy it is to install.”

All you need to carry out the periodic filter maintenance is a K&N recharge kit like the 99-5000 filter care kit. The kit includes filter cleaning fluid and filter oil.

The SU-1409 filter fits the following models:
