S178

Flat, loose and even faster, the new S178 Stabilizer is a high speed upgrade to the Sonar Foil System for experienced riders. We recommend pairing the S178 with Front Wing size HA950, or smaller. The S178 has a higher aspect ratio than the S208, which means less drag, and the flatter rondure (front view) enables more manoeuvrability. 

As we’ve increased our front wing range, we’ve needed to match the lift force of the front wing with the stabilizer. While your front wing creates vertical lift, your stabilizer has a downward acting force, which prevents the front wing from nose-diving. A larger stabilizer translates into more front foot pressure, while a smaller stabilizer equals less front foot pressure.

The North stabs are mounted on top of the fuselage, which helps them to avoid turbulence from the flow of the front wing, creating a smoother ride. This top mounting also gives the rider an early breach warning - the stab pierces the water surface first, giving you a better chance of recovery before your front wing gets too high. 

Like the Front Wings, all Sonar Stabilizers are pre-preg carbon construction, ensuring optimal stiffness and direct performance. The thin profile section reduces drag, while the material properties help maintain structural integrity and rigidity. 

Stabs have a huge influence on performance. As you progress to smaller wing sizes, we recommend changing to a smaller stabilizer to be more manoeuvrable. Experienced riders will really feel the difference. A new tail can have a big impact on your style.

S208

Flat, loose and fast, the new S208 Stabilizer is another high performance upgrade to the Sonar Foil System for experienced riders. The S208 has a higher aspect ratio than the S210, which means less drag, and the flatter rondure (front view) enables more manoeuvrability.

It has a higher aspect ratio than the S270, which means less drag, and the flatter rondure (front view) enables more manoeuvrability. The S238 is designed to match the new MA1200/MA1500 and larger HA front wings, giving your setup a faster and more responsive feel.

Worth it! Love these filters.
I love K & N air filters and always install them in my cars. This eliminated my cars Turbo lag in my 2019 Honda Civic Ex which has a 1.5L Turbo. Acceleration has improved and makes the car louder (I also have dual exhaust) I love how you don't have to change or clean it for 50,000 miles!! I know it's expensive but will last forever! Only issue was it was very difficult to install and a pain but this is more Hondas fault as I could not fully remove the plastic case where this filter goes under the hood even with tools.

More power and better mileage
Put this in my 2017 CRV and have noticed much more pickup and better mileage overall. Usually I average 22mpg with mixed driving and this has me hovering around 25mpg and I get to have extra power on top of that. Install was straightforward and a breeze. Whole project is done in ten mins and your car is instantly more fun and getting improved MPGS
