Some links on AmpAuto pages - particularly those pointing to OBD2 scanners, replacement parts (like ignition coils, oxygen sensors, spark plugs), and other automotive tools - are affiliate links. If you click one of these links and purchase a product on Amazon (or another partnered retailer), we earn a small percentage of the sale.
The price you pay is exactly the same. Affiliate commissions are paid by the retailer, not by you, and are factored into the retailer's standard pricing.
AmpAuto is a small independent project. Affiliate revenue helps cover our hosting costs, AI processing fees, and ongoing development without forcing us to plaster the site with intrusive ads or paywall the free diagnostic tool.
We only link to products we believe are genuinely useful for the diagnostic situations we describe. We don't recommend products we wouldn't use ourselves, and we never let an affiliate relationship change our diagnosis or repair guidance. The cause of your check engine light is the cause of your check engine light - the parts we recommend are based on what actually fixes the problem, not what pays us the highest commission.
AmpAuto (operating from ampauto.io) is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.
Our Amazon Associates tracking ID is ampauto20-20.
We may add additional affiliate programs in the future (such as RockAuto, AutoZone, or specialty tool manufacturers). When we do, this page will be updated to reflect those relationships. All affiliate links on the site will continue to be clearly marked or contained within content that discloses the affiliate relationship.
This disclosure is provided in accordance with the U.S. Federal Trade Commission's Endorsement Guides (16 CFR Part 255).
