Finding the correct diesel engine parts is not always simple.
Between OEM variations, engine models, CPL numbers, ESNs, VIN prefixes, and multiple part categories, it is easy to end up with results that are either too broad – or too specific.
That is exactly why Highway and Heavy Parts built the HHP Product Finder.
Instead of manually searching through thousands of products, the Product Finder helps narrow results based on your engine and application.
The goal is to make diesel engine parts lookup faster, easier, and more accurate: helping reduce downtime and simplify the ordering process for customers.
Where to Find the Product Finder
The Product Finder is located directly on the Highway and Heavy Parts website.
To access it:
- Click the “Shop” button
- Select “Product Finder”
From there, the filtering process begins.
Step 1: Select Your OEM
The first step is selecting the engine manufacturer or OEM.
Examples may include:
- Caterpillar
- Cummins
- Detroit Diesel
- International/Navistar
- Mack
- Mercedes
- Paccar
- Perkins
- Volvo
- and more
This immediately narrows the available engine options and part categories.
👉 If you are not completely sure of your engine details yet, starting with the OEM is still enough to begin filtering results.
Step 2: Choose Your Engine Model
Next, select the engine model.
Examples include:
- C15
- ISX
- DD15
- DT466E
- Series 60
- MX13
At this stage, the Product Finder begins narrowing parts specifically for that engine platform.
This is important because many components can vary significantly between engine families—even within the same manufacturer.
Step 3: Select Your Part Category
After selecting the engine, choose the category of part you are looking for.
Examples include:
- Cylinder Heads
- Fuel Injectors
- Turbochargers
- Engine Rebuild Kits
- Gaskets
- Oil Pumps
- Camshafts
👉 This step helps remove unrelated products and focuses only on the component category you actually need.
Step 4: Use CPL, ESN, or VIN Prefix Filters (Optional)
For more precise filtering, the Product Finder also allows you to filter using:
- CPL numbers
- ESN prefixes
- VIN prefixes
This helps narrow results down even further for engines with multiple configurations or production variations.
However, this step is optional.
👉 You can skip these filters if you do not have that information available.
The system is designed to work whether you want to search broadly or get highly specific.
You Can Be as Broad or Specific as You Want
One of the biggest advantages of the Product Finder is flexibility.
You can:
Keep It Broad
Example:
- OEM only
- OEM + engine model
This works well if you are still diagnosing the issue or comparing options.
Narrow It Down
Example:
- OEM
- Engine model
- Part category
- CPL/ESN/VIN prefix
This helps identify highly specific parts for a particular engine configuration.
👉 The more information you provide, the more refined the results become.
This flexibility allows customers to quickly narrow down options without needing every engine detail upfront, which helps speed up the process when time matters.
Final Results and Product Popup
Once your filters are selected, the Product Finder displays matching products in a popup results window.
This allows you to:
- Review available options
- Compare products
- Open product pages
- Continue narrowing your search if needed
The goal is to simplify the process without forcing users through unnecessary steps.
Why This Matters
Diesel engine applications are rarely one-size-fits-all.
The same engine family may have:
- Multiple CPL variations
- Different turbo configurations
- Different fuel systems
- Different gasket setups
- Different injector calibrations
Using a guided filtering system helps reduce:
- Incorrect orders
- Fitment confusion
- Time spent searching
👉 Faster part identification can help reduce downtime, avoid repeat ordering issues, and simplify the overall purchasing process.
Built for Both General and Specific Searches
Some customers know every engine detail.
Others only know:
- The OEM
- The engine model
- Or the type of part they need
The Product Finder was designed to support both situations.
That means you can:
- Start broad
- Narrow results later
- Skip steps if needed
- Or filter aggressively from the beginning
Final Takeaway
The HHP Product Finder was built to simplify diesel engine parts lookup without removing flexibility.
By allowing users to filter by:
- OEM
- Engine model
- Part category
- CPL/ESN/VIN prefix
the system helps narrow thousands of products into more relevant results faster – making the ordering process easier while helping reduce downtime.
Whether you are searching generally or looking for an exact engine configuration, the Product Finder is designed to help streamline the process.
