This custom-engineered 2nd injector kit will bring your engine's throttle response and power range to the next level. Made from billet aluminum for strength and weight savings. Carefully assembled by hand, into a real genuine KTM OEM airbox for long-lasting performance. A Vortex ECU with our custom 2nd injector mapping is required to run our 2nd injector kit! Click here to browse our ECU product page.
If you already have a Vortex ECU, you can reflash your current Vortex ECU Here.
Please note: We can only accept ECUs that were made in 2022 or newer, due to compatibility issues.
We now have a meticulously made, step-by-step installation manual. We will send a QR code with your 2nd injector kit, for an online PDF.
We highly recommend using one of our high-quality race fuel options, from either VP or ETS. This insures the most reliable performance gains. With Pump gas, you will still highly benefit from a 2nd injector. That being said, pump gas can vary from one manufacturer to another, possibly leading to inconsistencies in performance.
It is recommended to use a Twin Air PowerFlow filter kit, to get the most benefits out of our 2nd injector setup.

Customer Reviews
I recently purchased a 2nd injector and vortex remap for my 2025 Husqvarna FC 250. It made a huge difference across the power band! The Husky is very linear and it stayed that way, just more power everywhere. I also noticed more over rev on top. This is much better than just buying a pipe. It was easy to install with clear and concise instructions. I have zero complaints. While not cheap, its still money well spent for noticeable power gains.

Let customers speak for us
Works as advertised, seems kinda pricey for such a small part. I’m not a machinist so might be right for making and thinking of it!!!
Works like it should and vent line or fitting dosent come off the gas cap
I found on Facebook and ordered right away. Great quality, makes gas cap easy to remove with out twisting vent hose. No more pinched vent tube.
Looks great and works as it should .
Absolutely incredible. Local privateer and this kit allows you to have a competitive 250. Worth every penny on my
This ECU is great! Made my 250 a whole new bike!
got updated mapping on the Vortex for 2025 CRF45r and its a total different bike!!!
This is the 6th ECU Chad/XPR has done for me and I'm still amazed at what it does to improve rideability and power. Best mod you can do hands down. People say "I don't need more power" I tell them there's a map for that too and its the connectivity and reduced engine braking that will make the biggest differences in consistent controlled cornering.
Hands-down, one of the best performance products ever put on a bike
I’m a small time privateer from Southwick Mass just trying to race a couple nationals every year, I recently purchased this dual injector/Vortex kit from xpr. being a typical racer “always looking for more” I played with the settings a little bit and found myself going backwards. Chad took the time out of his busy day to help me out and what I got out of it was, don’t mess with his settings, and an explosive 250f that I absolutely feel 100% confident will be competitive at the races. Track tested as we were chatting and I was absolutely blown away. Whether you’re a pro looking for a reliable, affordable, upgrade, or just a weekend warrior looking for more excitement on your yz250f. BUY THIS KIT!!! It is worth every penny!!! Chad seems like an awesome guy and I am absolutely beyond please I chose to work with him and XPR on this years race bike!!!! It’s an easy 5 stars for me. Thanks again!!!
Aluminum water spout fits perfectly and was easy to install. This part should be aluminum from the factory.
With XPR Custom Maps, my cornering and handling on the entire track have improved significantly. It gives me confidence. I love it
I’m on my fourth 350, and I finally decided to pony up and buy an ecu from XPR. All I can say is, WOW, what a difference it makes! No more flame outs, and the throttle response across the whole rpm range is incredible. It can lug like a manageable 450, but still revs to the moon like a hopped up 250. It just feels so crispy. Worth every penny - take the plunge and you won’t regret it.
Did this XPR Dual Injector setup with XPRs Vortex Tuned ECU and it made huge improvements. Expect more bottom,mid range, and top end without the feeling loss of power even at over rev. This setup will elevate your riding experiance.
It's really a nice add on to my Y Z
