The AIR4ORCE tunable intake system completely replaces your existing stock airboot with a custom-designed airboot that offers the maximum air volume for increased horsepower and the benefit of adjustable velocity stacks to allow you the ability to fine tune the power delivery for rider preference and/or track conditions. There's simply nothing else like it out there, which is why you see it being run by many of the top racers and teams. The AIR4ORCE is currently used by Monster Energy Kawasaki, GEICO Honda, Troy Lee Designs/Lucas Oil/Honda, Rockstar Suzuki and many more.
- Tunable Intake System to increase horsepower.

- Short velocity stack: Stronger mid-to-top power with better acceleration.
- Includes clamps and gaskets where necessary.
The AIR4ORCE Story...
The decision to enter the four-stroke market was not taken lightly. It was immediately clear that as a company, Moto Tassinari wanted to continue to build on the success of the VForce3 reed valve system. Moto Tassinari wanted to offer a product to the racing community that they would in turn feel was an essential part of their engine performance and on-track success. Much like the VForce3 reed valve system has been previously. Moto Tassinari feels they didn't disappoint and they're confident you'll agree.
The AIR4ORCE tunable intake system has received 1000's of hours of development and fine-tuning to bring you the highest level of performance, while also allowing a simple straight forward installation. Every characteristic of the AIR4ORCE has been taken into consideration, a fact you'll notice as soon as you open the box. Moto Tassinari hopes you enjoy the new AIR4ORCE tunable intake system as much as they enjoyed developing it from a concept on the drawing table, to a vital part of a winning motorcycle.
What are Velocity Stacks?
The most unique feature of the AIR4ORCE tunable intake system is the ability to fine-tune the power delivery via interchangeable velocity stacks. However, that concept might be a little unfamiliar for some not as experienced with four-stroke motor performance. Let Moto Tassinari explain the concept below:
A velocity stack is a device of differing lengths which is fitted to the air entry of an engine's intake system, carburetor or fuel injection. It is designed to:
- Allow smooth and even entry of air at high velocities into the intake tract with the flow stream adhering to the pipe walls.
- Modify the dynamic tuning range of the intake tract by functioning as a resonating pipe which can adjust the frequency of pressure pulses, based on its length, within the tract.
Great product - the powerband was improved with the long stack...
One of the Best Mods you can fo to your 4 Stroke !!
There this on my 2010 YZ250F and went with the stack to improve the top end. Install was super easy. I noticed a huge change to my bike's power during my first ride at the track after install and I couldn't be happier with how much improvement I saw. If there was a bike to put this product on, it is definitely a YZ250F. It greatly reduced the flat feeling that was there in the higher gears and the hit off closed throttle is awesome in any gear!
****HOWEVER****, once i got the boot installed and was wiping off the finger prints, the MT logo on the boot straight ripped off! The raised red pieces on the logo are glued on like garbage and nothing I tried would get it to stay on. Spending $300.00 dollars on what amounts to $10.00 of rubber and having this happen is a huge bummer. I've tried to call their customer service line on three occasions with no luck of actually getting anyone. For this reason, I gave the product 4 stars instead of 5. Putting aside this single shotty aspect of the air boot, I would say the product is a definite 5.

Items that may help more with the bog issue:
1. Jet Kit
2. Accelerator Pump Cover
3. Fuel Mixture Screw
I would also recommend taking your bike to a shop or mechanic to have it re-jetted and tuned if you do not have previous experience doing this yourself.
