Comments:
K4 Incinerators were designed to get Quad boards up onto the plane to get you out but still allow an excellent turning radius and grip on the wave (with places like Pozo in mind).  K4 say...

The Incinerators. The best choice for your quad fin board! A narrower base for higher speeds and lightning fast direction changes, combined with a larger area tip for more hold and power. Designed with Adam Lewis who’s been looking to get the best performance from his quads.

And Now the Assymetrical Incinerator!The Asymmetric Incinerator front fins! More power, more drive, more speed, less drag. These are something special!

Made from our ‘super stiff’ material the A.I’s are much like the rest of the Incinerator range – slim, high aspect and fast.
The A.I. fin has a similar template to the Incinerator front but with a slightly wider chord. It has a 30/70 asymmetric foil optimised for quad set ups, but has also been found to work exceptionally well in thrusters.
Choose the degree depending on your boards box angles. Use the toe in calculator to find your boards box angle:
Note that quads require less toe in than a thruster to help alignment with the rears.
 
Then select the correct degree A.I. with help from the tuning guide
