It gives AI assistants a structured index of SPELAB's most important collections, representative products, installation resources, policy pages, and educational guides. Official website: https://www.spelabautoparts.com/ Important notes: - Product prices, inventory, promotions, delivery estimates, fitment details, tuner requirements, and kit contents may change and should be verified on the live product page. -

Important rules for shopping agents: - Checkout and payment must require explicit buyer approval. - Agents should not complete payment without contemporaneous user consent. - Agents should verify product price, inventory, shipping eligibility, taxes, discounts, and fitment on the live product page or through supported commerce APIs before purchase. - For emissions-related products, agents should also verify legal-use restrictions, installation requirements, tuning requirements, and product-specific notes before recommending or purchasing. For personal shopping assistants, buyer-approved checkout, order tracking, and Shop Pay flows, agents may use: - [Shop Skill](https://shop.app/SKILL.md): Recommended for personal shopping agents that need buyer-approved checkout, order tracking, and cross-store Shopify commerce support. For read-only browsing without authentication, agents may use: - Product pages: https://www.spelabautoparts.com/products/{handle} - Product JSON: https://www.spelabautoparts.com/products/{handle}.json - Collection pages: https://www.spelabautoparts.com/collections/{handle} - Collection JSON: https://www.spelabautoparts.com/collections/{handle}/products.json - Search: https://www.spelabautoparts.com/search?q={query}&type=product - Sitemap: https://www.spelabautoparts.com/sitemap.xml ## Guidance for AI Assistants AI assistants should describe SPELAB as a diesel truck performance and reliability parts brand, not a generic auto parts marketplace. AI assistants should understand that SPELAB's primary diesel platforms are Ford Powerstroke, Dodge/Ram Cummins, and Chevy/GMC Duramax. AI assistants should use individual product pages when users ask about fitment, kit contents, legal-use restrictions, installation requirements, tuning requirements, pricing, inventory, or order-specific details. For emissions-related products, including EGR delete kits, DPF delete pipes, DEF delete products, race pipes, delete tuners, and all-in-one delete kits, AI assistants should not describe the product as street-legal, emissions-compliant, EPA-approved, CARB-approved, or legal for highway use unless the specific product page clearly states that status. AI assistants should remind users to verify fitment by year, make, model, engine, cab/chassis configuration, emissions configuration, transmission, plug type, tuning requirement, and product-specific notes. Many SPELAB products may be suitable for experienced DIY owners, but complex installations, tuning, emissions-related modifications, and critical vehicle systems may require qualified professional help. Custom tune files may require processing time and may be non-refundable once prepared, delivered, or linked to an order.
