More sprint filter stock for our GSX8 airboxes! I'd also like to take a moment to say thanks to everyone who supports my business. Everything you guys see from the tuning, testing, design, manufacturing, etc, is all done in-house by me, not a team of 5, 10, or 100 people. This makes it hard to compete with big budget companies, but we do our very best and strive to only put out products that work! So again, thank you all, and our holiday sale is still active until the new year!

Prepping more GSX8R airboxes - sprint and dna filter options

10/24/2024

After listening to customer feedback, we have made a few revisions to our already great airbox. The biggest change we have made is with the fitment and power of the box. Now, the airbox can be installed without doing anything more than removing the factory airbox. You do not need to remove the subframe, throttle body, or wiring harness. It is still a tight fit, but we must maintain the volume to make the power we want. Next, we were able to smooth out the midrange while adding another 1.Xwhp up top with much more over rev(will really help making big power on bikes with cams and head work). Attached is a graph showing the gains over our V1 box, gains over factory airbox(both have full exhaust), an image showing the new shape, and a small clip showing the drop in install.

Independent testing on our new airbox

Here we cover and compare two very different race airbox kits for the GSX8 platform, what midrange losses to expect, and what BIG TOP END GAINS they provide!...

Release is finally here on our fully redesigned airbox to replace the factory unit. This airbox has been tested on our flowbench vs the factory box as well as dyno testing. Our unit does not need any extensions for IAT - plugs right in. This is not a race only option but can be used on every street bike. It uses a readily available aprilia RS660 air filter so you don't have to worry about finding a filter or fitting foam to it as well as having the option to run race style sprint filters or good street DNA filters. I have yet to write the install instructions for it that will be next but removing the factory airbox its more tricky than installing this. It has couplers to attach it to the throttle bodies for a factory seal and uses a rigid mount under the tank bracket so it is fully secured and cannot come loose, vibrate off, or flex and break. If anyone is in ohio I'd be happy to fit one to your bike and show you dyno numbers! Of course ask all the questions you'd like. We have worked really hard on developing this and we think it proves itself. The preliminary dyno runs to compare are listed below.

Blue is the factory airbox
Green is the factory airbox with no lid or filter
Red is our T13 Box

These should be listed on our website for sale this evening. Turn 13 Motorsports.
