Availability: Out of stock.


Quick Overview


Product Description

NEW BLUETOOTH VERSION COMING SOON! Remote Enable/Disable and boost gauge.  The same price and performance with new features!

We proudly present our Ultimate MACSBOOST Performance Kit for the Honda Aquatrax 12 series Watercraft!

The Stage 2 kit adds the MACSBOOST Intercooler and UNI air filter set to the Stage 1 Module and Impeller combo. The intercooler dramatically increases horsepower over the stage one kit.  Boost builds much faster than stock with the free breathing large diameter intake piping and free flowing intercooler.  Intake temperatures drop over 100 degrees fahrenheit vs the puny stock unit. Low octane fuel performance is also greatly improved. 

With the tremendous cooling capacity of the MACSBOOST Intercooler and the MACSBOOST Module installed, you have the ability to crank the boost to the maximum. With 98 octane fuel, you can increase horsepower output to 215! thats 50 over stock! With 93 octane, you can increase horsepower output 40+.

With our stage II kit, you get an incredible increase in horsepower, with stock levels of reliability. Peak RPM remains below or just at the stock rev limiter, and intake temperatures are lower than that of the stage 1 kit.  With our exclusive MACSBOOST module, boost control is retained in the stock ECU and can be reduced due to knock, etc.   If you do not have the proper octane, boost is automatically reduced electronically to a safe level. No tuning or headaches come with the kit. Installation is easy and reversible.   You drill no holes or make any permanent modifications.  This kit is completely removable without a trace.

Do you have an R-12X?


If so, we highly recommend our pump wedge to complement this kit.  You get more top speed and better fuel economy with one simple part!
