Legal-use classifications
Some products are identified as:
- Race use only
- Competition use only
- Off-road use only
- Not legal for pollution-controlled vehicles
These products are published only after manual compliance approval.
Products we do not sell
- DPF delete kits
- EGR delete kits
- DEF or SCR delete products
- Delete tuning
- Emissions-code suppression products
- Devices designed to bypass emissions monitoring
- Sensor simulators intended to defeat or bypass emissions controls
A legitimate replacement sensor, diagnostic device, or testing tool is published only after an administrator confirms it is not designed to defeat emissions controls.
Emissions-sensitive product requirements
- Admin approval before publication
- Legal-use classification
- Manufacturer documentation
- Supplier documentation
- State restrictions
- Street-use status
- CARB status when relevant
- Compliance-review date
- Reviewer identity
Applicable restrictions are shown in your cart, in the checkout acknowledgment, and on your order confirmation. Competition-only products require a separate acknowledgment.
Orders that cannot legally be shipped to your location are canceled and refunded or voided.
California
Until CARB requirements are fully reviewed, emissions-sensitive products are not sold into California unless the product has verified documentation permitting the sale.
CARB Executive Order information is stored when applicable. Products with missing required documentation remain unpublished or restricted.
