Description

Our TST Industries WORX program has lead the efforts in achieving maximum power gains out of the 321cc Yamaha R3 engine, resulting in an ASRA MOTO3 National Championship and a bench full of trophies. As part of that effort, modifying the airbox to enable more airflow to the engine proved to be a key component to our success, and now you can do the same to your Yamaha R3 in your strive for track day dominance. Both left and right airbox covers are precision-cut and hand-finished and easily install using the OEM hardware. When combined with a high-flow air filter, full exhaust system, and proper tune, our exclusive TST WORX Airbox Covers play an important role in improving the performance of your R3 engine across the entire RPM range.

* This kit works best when paired with a high-flow race air filter, exhaust system, and proper tune.

  • (2) TST WORX Modified Airbox Covers (left and right)

This kit provided the airbox covers only and does not include the entire airbox assembly

Q: What is a refundable "core charge"?
A: A core charge is a partial refund that we issue in return for providing us with your OEM, non-modified, airbox covers that we can then use for remanufacturing. Your airbox covers MUST be in good condition and free of any contaminants, debris, or damage in order for us to consider them usable.

Q: If I want the $20 refund, do I have to pay to ship my stock airbox covers to you?
A: Yes - you are fully responsible for properly packaging and shipping your airbox cover to our facility in Florida. You can return them using the TST packaging you received as part of your order. You MUST include your original packing slip in the package for us to process your refundable core charge.

Q: What do I need to include in the package to get my refundable core charge?
A: Please include your unmodified OEM airbox covers (both left and right covers) and your TST packing slip showing you ordered the TST WORX Airbox Covers. Again, your airbox covers MUST be in good condition and free of any contaminants, debris, or damage in order for us to consider them usable. If they do not meet these requirement, we will not be able to use, will not issue the refundable core charge, and will not ship them back.

Q: Can I do this without making any other changes to my bike?
A: Sure you can, but to really get the proper benefits of this modification, you'll need to pair this with a full exhaust, high-flow air filter, and a proper tune.

Q: Do I have to leave the side fairings off like in the photos?
A: Yes - that enables the additional airflow to enter the modified airbox. We know it's not the most attractive modification, but championships are built on performance, not looks.

Q: I'm located outside of the United States. Will I have to pay duties on this item?
A: Some countries charge additional fees when a package is imported and delivered to the recipient. We have no way of knowing or estimating what these fees will be. It is the buyer's responsibility to cover these additional costs.

Q: What is your return and warranty policy?
A: Please read over our policies thoroughly on our terms and conditions page BEFORE making your purchase.
