ACES and PIES: The Complete Guide for Auto Parts Data
ACES and PIES are the two data standards that auto parts manufacturers, distributors, and retailers use to describe which vehicles a part fits and what the part is. This guide explains ACES and PIES, the most common errors, and how a PIM automates ACES and PIES files.
The automotive aftermarket industry is a dynamic sector that includes all parts and services purchased for vehicles after the original sale. This growth is driven by
- Increasing vehicle age
- Technological advancements, and
- Rising demand for customization and performance upgrades.
This exponential growth brings the challenge of managing an ever-expanding array of products and their associated data. Accurate, consistent product information is essential for aftermarket businesses to improve customer satisfaction and meet industry standards.
This is where ACES (Aftermarket Catalog Exchange Standard) and PIES (Product Information Exchange Standard) come into play. Developed by the Auto Care Association, these standards provide a structured framework for exchanging product information across various channels, ensuring consistency, accuracy, and efficiency.
However, managing ACES and PIES data can be complex and resource-intensive, especially for businesses dealing with a vast product portfolio. Integrating a robust PIM system tailored to ACES and PIES compliance can streamline these processes, reduce errors, and improve overall operational efficiency.
Let’s dive deeper into ACES and PIES, the challenges of managing them, and how integrating them with a PIM system can redefine product data management in the automotive aftermarket industry.

Understanding ACES and PIES
ACES (Aftermarket Catalog Exchange Standard) and PIES (Product Information Exchange Standard) are the backbone of product data communication in the automotive aftermarket industry. They provide standardized formats for exchanging information among manufacturers, distributors, retailers, and other stakeholders, ensuring everyone speaks the same language when it comes to product data.
Example Scenario:
An auto aftermarket manufacturer produces a new type of brake pad compatible with multiple vehicle models. They must share comprehensive, standardized information so distributors and retailers can accurately list and sell the product.
Here’s how ACES and PIES facilitate this process:
- ACES provides application data detailing which vehicles the brake pad fits. This includes year, make, model, and other relevant vehicle attributes.
- PIES would provide detailed product information, including part numbers, descriptions, dimensions, pricing, images, and other marketing data.
By using ACES and PIES standards, the manufacturer ensures downstream partners have accurate, consistent information, reducing the risk of errors, returns, and customer dissatisfaction.
What is ACES?
ACES (Aftermarket Catalog Exchange Standard) is the North American industry standard for communicating product fitment data in the automotive aftermarket. Developed by the Auto Care Association, it provides a standardized format for conveying which vehicle-specific parts and accessories are compatible, ensuring precise and consistent application data across the supply chain.

Critical Components of ACES:
- Vehicle Configuration Database (VCdb):
- A comprehensive database that contains standardized vehicle information, including year, make, model, engine types, and other relevant attributes.
- Ensures uniformity in vehicle descriptions, reducing ambiguity and errors in product listings.
- Product Classification Database (PCdb):
- Categorizes products into standardized classes, facilitating more accessible organization and retrieval of product information.
- Qualifier Database (Qdb):
- Provides additional details or conditions related to product fitments, such as specific trim levels or optional equipment requirements.
A company manufactures a headlight assembly suitable for multiple versions of the Ford F-150. Using ACES, the manufacturer can accurately specify all compatible models, including variations in year, engine type, and trim level. Distributors and retailers then receive this standardized data, ensuring that customers searching for a replacement headlight for their specific F-150 model find the correct product without confusion.
What is PIES?
PIES (Product Information Exchange Standard) complements ACES by providing a standardized format for communicating detailed product information in the automotive aftermarket industry. While ACES focuses on fitment data, PIES covers a product’s descriptive, pricing, and marketing aspects, ensuring comprehensive and consistent information across all channels.

Critical Components of PIES:
- Product Attributes:
- Includes detailed specifications such as dimensions, weight, materials, and performance characteristics.
- Digital Assets:
- Encompasses images, videos, technical documents, and other multimedia resources that support product marketing and customer understanding.
- Pricing and Packaging Information:
- Details various pricing structures, packaging dimensions, and quantities.
- Marketing Descriptions:
- Provides compelling product descriptions, features, benefits, and other marketing copy to enhance product appeal.
For example, consider a company launching a new performance exhaust system. Using PIES, they can provide exhaustive details such as:
- Product Specifications: Material type (e.g., stainless steel), dimensions, weight, and performance enhancements.
- Digital Assets: High-resolution images from various angles, installation videos, and sound clips demonstrating the exhaust note.
- Pricing Information: MSRP, dealer pricing, bulk purchase discounts, and packaging details.
- Marketing Copy: Engaging descriptions highlighting the benefits, such as increased horsepower, improved fuel efficiency, and enhanced sound.
