Frequently Asked Questions

Do these bolt directly into the factory locations?

Yes. Both sensors use the factory mounting points on the exhaust. No drilling, no custom brackets — screw them in and you're done.

Will the factory connectors plug in without modification?

Correct. These use OEM-style connectors that match the factory harness. No adapter wiring required.

What's the return process if one sensor fails after installation?

Contact ModSupply directly with your order number and photos of the failed unit. Warranty coverage and return shipping are handled on a case-by-case basis — have your receipt ready.

Products received may vary slightly from images due to manufacturing tolerances or supply chain variables.
